TL;DR — 7 things to know before reading
Most LinkedIn connection campaigns stop at the connection request. A prospect accepts, and nothing follows. That is a significant missed opportunity — acceptance is a warm signal, and a well-timed follow-up converts that signal into a conversation at a far higher rate than any cold message to a stranger.
Aimfox automates the follow-up sequence so every accepted connection receives a planned series of messages at configured intervals. You write the messages once, set the delays, and Aimfox handles delivery and stops automatically when a prospect replies. This guide covers how to structure an effective sequence, how to build it in Aimfox step by step with specific sub-tasks and benchmarks, what to track to know if it is working, and how to troubleshoot the problems that prevent sequences from performing as expected.
The mechanics of Aimfox's sequence builder are straightforward. What separates high-performing sequences from average ones is the combination of the right delay structure, message framing that fits each step's purpose, and the discipline of not over-sequencing a prospect who has already shown they are not interested. This guide covers all three, plus the advanced tactics that practitioners use to improve sequence performance beyond the defaults.
A follow-up sequence is a series of LinkedIn messages automatically sent to a prospect after a trigger — typically after they accept your connection request. Each step has:
When a prospect replies at any step, Aimfox stops the sequence for that person and marks the conversation as active in Unibox. No manual intervention is needed.
The sequence is tied to the campaign. Every prospect in that campaign who accepts your connection request enters the same sequence. If you want different sequences for different audiences (enterprise vs SMB, technical vs non-technical), create separate campaigns with separate sequences rather than trying to serve both audiences from one campaign.
| Step | Timing | Purpose | Length |
|---|---|---|---|
| Step 1: Post-connection message | 1 day after connection accepted | Warm intro, establish context | 3–5 sentences |
| Step 2: Value-add message | 4–5 days after step 1 | Provide something useful, no ask | 3–5 sentences |
| Step 3: Soft ask | 5–6 days after step 2 | Request a short conversation | 4–6 sentences |
| Step 4: Final follow-up | 6 days after step 3 | Last touch, leave the door open | 2–3 sentences |

Running more than four steps without a reply typically indicates the prospect is not interested at this time. Continuing past four steps increases the risk of the prospect reporting the messages, which damages account standing. After four unreplied steps, mark the prospect as finished in the sequence and remove them from future campaigns for a minimum of 90 days.
In your Aimfox campaign, go to Sequence or Follow-Up Steps in campaign settings. The sequence builder shows the connection request as Step 0. Your follow-up steps begin at Step 1, triggered after a connection is accepted.
Sub-steps:
Benchmark: The sequence builder should load within 5 seconds. If it does not, refresh and try again; a slow load can indicate a session timeout that would cause step saves to fail silently.
Click Add Step and write Step 1. This message goes to every prospect who accepts your connection request.
Step 1 should:
Set the delay to 1 day after the connection is accepted. This is long enough to feel natural rather than automated, but short enough that the connection is still fresh in the prospect's mind.
Sub-steps:
Benchmark: A well-configured step 1 message takes 15–20 minutes to write and refine. If you are spending more than 30 minutes on step 1 copy, you are likely over-engineering it. The post-connection message should be natural, not polished to the point of sounding corporate.
Message framework for step 1:
"Hi , glad to be connected. [One sentence on what you do and who you typically work with]. [One sentence on why you reached out to this specific person, using their role or company context]. Happy to share more if timing is right."
This 3-sentence structure works because it establishes context without making an ask, and it leaves the door open without being pushy.
Four to five days after Step 1, send a value-add message. The purpose of this step is to provide something useful before making any ask.
Value message approaches that perform well on LinkedIn:
This step is not transactional. Prospects who are not ready to buy often engage at this step because it asks nothing of them. Prospects who are interested may reply here, stopping the sequence automatically.
Set the delay to 4–5 days after Step 1. Enable the condition: Only send if no reply received.
Sub-steps:
Benchmark: Step 2 should produce replies at a rate of 4–8% from accepted connections who received step 1 without replying. Reply rates below 3% from step 2 typically indicate the value content is not sufficiently relevant to the audience.
Message framework for step 2:
", [specific insight relevant to their function/industry]. [One sentence explaining why this matters for teams like theirs]. [Optional question that invites a reply without making a commercial ask]."
Five to six days after Step 2, make a low-commitment request for a conversation: a 15-minute call, a specific question to answer, or a link to a short video. The lower the commitment required, the higher the conversion rate from this step.
The ask should:
Enable: Only send if no reply received.
Sub-steps:
Benchmark: Step 3 should produce replies at 3–6% of prospects who reached it without replying to earlier steps. If your step 3 reply rate is below 2%, the ask may be too large (asking for too much commitment) or the value established in steps 1 and 2 is not sufficient to generate trust.
Message framework for step 3:
", worth asking directly: given [specific context from steps 1-2], would 15 minutes to discuss [specific outcome] be worth your time? Happy to send a link to book if so."
Six days after Step 3, send a brief closing message. At this point the prospect has received three messages without responding. A final note acknowledges this and removes any pressure while leaving the door open for future contact.
Keep it to 2–3 sentences. Do not pitch again. Close with something like: "Happy to reconnect if timing changes on your end."
Enable: Only send if no reply received. After this step completes without a reply, Aimfox marks the prospect as finished and the sequence ends.
Sub-steps:
Benchmark: Step 4 closing messages typically produce the lowest reply rate of all steps (1–3%), but they serve an important function: they close out the sequence for unresponsive prospects cleanly rather than leaving the sequence open indefinitely.
Message framework for step 4:
", I've reached out a few times — I'll leave this here for now. If timing ever changes, happy to pick this up. Best of luck with [relevant context from their role or company]."
Confirm that reply detection is active in your campaign settings. This is the mechanism that stops the sequence when a prospect replies. Without it, a prospect who responded to Step 1 could receive Steps 2, 3, and 4 anyway — which looks like you are ignoring their messages.
Sub-steps:
Benchmark: Reply detection should stop a sequence within 5–30 minutes of a prospect's reply being received on LinkedIn. If it takes longer than 30 minutes, LinkedIn's API polling interval may be set to a longer cycle — check Aimfox's settings for polling frequency.
Before activating:
Activate the campaign. Aimfox sends connection requests and follow-up messages automatically as prospects move through the sequence.
Sub-steps:
Benchmark: The full sequence review and activation process should take 20–30 minutes for a 4-step sequence with 4–5 test prospect previews. Rushing this step is the most common cause of misconfigured sequences that produce low performance.
Different campaign goals require different sequence framing. Here are frameworks for the three most common B2B LinkedIn sequence goals:
The sequence builds credibility through the first two steps and makes a specific ask in step 3. Each step references the prospect's specific role or company context.
The sequence is softer throughout and the ask in step 3 is for an exploratory conversation rather than a demo.
The sequence progressively reveals the role context. The connection request and step 1 should not name the specific title. See the full Aimfox recruiting guide for full candidate-specific frameworks.

"Running a 3-step follow-up sequence in Aimfox after the connection request converts accepted connections into active conversations at around 12–15%. Without follow-up, the same accepted connections produce almost no outbound-initiated conversations. The sequence does the heavy lifting after the handshake." — G2 reviewer, Aimfox reviews on G2
Aimfox holds a 4.6/5 rating on G2, with follow-up automation consistently cited as one of the most valuable features by agency users running high-volume campaigns. Woodpecker's multichannel outreach research shows that reply rates increase 40–60% when LinkedIn outreach is paired with cold email sequences — running Instantly email sequences in parallel with Aimfox LinkedIn sequences creates the multichannel effect that drives this outcome.
Symptoms: A prospect replies to step 1, but step 2 sends anyway. You have duplicate conversations where one is a reply thread and one is a new automated message.
Diagnosis steps:
Fix: Enable "Only send if no reply received" on all steps beyond step 1. This is the primary fix. If the issue persists with the condition enabled, contact Aimfox support to confirm reply detection is functioning correctly for your account. As a short-term workaround, manually pause the sequence for affected prospects in Unibox.
Symptoms: A prospect accepts the connection and receives all four messages within 24–48 hours rather than over 20+ days.
Diagnosis steps:
Fix: Re-configure each step with explicit day-based delays. Set step 1 to "1 day", step 2 to "4 days after step 1", etc. Save each step and confirm the campaign's sequence timeline shows the expected dates before activating.
Symptoms: The sequence completes for most prospects without any replies. The total reply rate across all steps is below 2%.
Diagnosis steps:
Fix: Run an A/B test: keep the existing sequence as Campaign A and write entirely new step 1 and step 2 copy for Campaign B with the same audience. Compare reply rates after 2 weeks. If Campaign B performs significantly better, adopt the new copy. If both perform similarly, the issue is likely audience quality rather than copy quality.
Symptoms: Prospects are accepting connection requests, but no sequence step 1 messages are being sent. Unibox shows accepted connections with no subsequent messages.
Diagnosis steps:
Fix: Confirm the campaign is active. If the campaign is active and the account is not restricted, check the daily limit settings and consider reducing the number of active campaigns competing for daily message capacity. If the LinkedIn account is restricted, follow the account recovery steps in Aimfox's documentation before resuming.
Symptoms: Step 3 appears to fire 3–4 days after step 2 instead of the configured 5–6 days.
Diagnosis steps:
Fix: Increase step 3's delay by the number of days that represent the discrepancy. If step 3 fires 2 days early, increase the configured delay by 2 days. Verify the fix by monitoring the next 5 prospects who go through the full sequence.
Symptoms: Prospects are receiving sequence messages from a different LinkedIn account than the one that sent the connection request, creating a confusing experience.
Diagnosis steps:
Fix: Reassign the campaign to the correct LinkedIn account. For prospects who already received a mismatched step 1 message, manually review their conversations in Unibox and decide whether to continue the sequence (acknowledging the different account) or to apologise and reset.
Symptoms: Sequence messages arrive as "Hi , ..." rather than "Hi Sarah, ..." OR arrive as "Hi , ..." with the name field blank.
Diagnosis steps:
Fix: Export a sample of the prospect list and check whether the first name column is populated for all rows. If some rows have blank first names, either fill them manually, remove those prospects, or configure a generic fallback ("there" is a common fallback for blank first names: "Hi there, ..."). If variable names are mismatched, update the variable references in the message to match the actual field names in the imported list.
Symptoms: Shortly after launching a sequence campaign, Aimfox reports that the LinkedIn account has received a warning or temporary restriction from LinkedIn.
Diagnosis steps:
Fix: Pause the campaign. Reduce the daily message limit for the account to the conservative range: 10–15 connection requests per day and 15–20 sequence messages per day for a new or recently connected account. Wait 24–48 hours for the warning period to pass before restarting at the reduced limit.
Aimfox does not offer native A/B testing within a single campaign. The workaround: create two identical campaigns (same audience segment split 50/50) with different step 1 copy. Run both for 2–3 weeks, then compare reply rates. The winning copy becomes the standard template for future campaigns in that audience segment.
This is particularly valuable for step 1 copy, where small changes in framing or personalisation approach produce large differences in engagement rates. Testing step 1 continuously across new audiences builds a library of copy approaches organised by reply rate, which dramatically improves the quality of future campaigns.
A single sequence for "B2B SaaS company decision makers" is less effective than separate sequences for "VP of Sales at Series B SaaS" and "Head of Marketing at Series A SaaS." The difference: each sequence uses step 2 value content specific to that function's challenges, making the message feel personally relevant rather than generically industry-aware.
Build a library of 4–6 audience segments with distinct sequences for each. The creation time is higher upfront, but reply rates improve enough across the portfolio that the investment pays off within 2–3 campaign cycles.
LinkedIn engagement is not uniform across days of the week. Per Woodpecker's cold email subject line study, engagement peaks on Tuesday, Wednesday, and Thursday for B2B outreach, with Friday afternoons and Mondays morning producing the lowest engagement. Configure Aimfox's working hours to restrict sequence sending to Tuesday–Thursday during business hours in the prospect's timezone. This reduces total sends per week but increases the percentage that are seen and acted upon.
Running parallel LinkedIn sequences (Aimfox) and email sequences (Instantly) to the same prospects increases total reply rates by 40–60% per Woodpecker's multichannel study. The coordination principle: stagger LinkedIn and email steps so they do not land on the same day. If LinkedIn step 1 goes on day 2 after acceptance, email step 1 should go on day 4. When a prospect replies on either channel, pause or cancel the other channel's sequence for that person immediately.
The contact list for this coordination comes from Quarvio, which provides both LinkedIn profile URLs (for Aimfox) and email addresses (for Instantly) in the same contact export.
Prospects who complete the 4-step sequence without replying are not necessarily uninterested — they may simply have been in the wrong moment. Build a separate re-engagement campaign that targets prospects who completed the primary sequence 90 days earlier without a reply. The re-engagement sequence is shorter (2 steps maximum) and acknowledges the prior outreach: "We spoke briefly [X weeks] ago about [topic] — I wanted to check back in as circumstances may have changed."
Per Aimfox reviews on G2, re-engagement sequences typically produce reply rates of 6–10% from prospects who did not respond to the original sequence, because timing and priorities change over a 90-day period.

How many follow-up steps should a LinkedIn sequence have?
Three to four steps is the standard for B2B LinkedIn outreach. Step 1 is the post-connection introduction, Step 2 provides value, Step 3 makes the ask, and Step 4 is the final note. More than four steps without a reply usually indicates the prospect is not interested at this time, and continuing risks the prospect reporting the messages.
What delay should I set between LinkedIn follow-up steps?
A minimum of 3–5 days between steps. The post-connection message should go 1 day after the connection is accepted. Subsequent steps should be 4–6 days apart. Shorter intervals feel like spam and reduce reply rates. If you are running parallel email sequences, stagger the LinkedIn and email steps so they do not land on the same day.
Does Aimfox automatically stop the sequence when a prospect replies?
Yes. Aimfox monitors each conversation thread. When a prospect replies at any step, Aimfox marks the conversation as replied and stops all remaining sequence steps for that person. Confirm reply detection is enabled in campaign settings before launching.
Can I edit a running sequence after the campaign is already active?
Yes, with caution. Editing a step that has already sent does not affect prospects who already received it. Editing a future step applies to all prospects who have not yet reached that step. Pause the campaign before making structural changes to avoid sending partially updated sequences to active prospects.
What is the difference between a connection campaign and a follow-up sequence?
A connection campaign handles only the connection request itself: who to send it to, what note to include, and at what daily volume. A follow-up sequence handles what happens after a connection is accepted: the series of messages that runs automatically after acceptance. They are complementary and both run within the same Aimfox campaign configuration.
Can I use the same sequence for different audiences?
You can, but performance will be lower than audience-specific sequences. A generic sequence written for "B2B decision-makers" produces lower reply rates than one written specifically for "Sales VPs at Series B SaaS companies." The more specific the audience, the more specific the value in step 2 can be, and the more relevant the ask in step 3. If you are running campaigns to multiple distinct audience segments, create separate campaigns with separate sequences for each.
How do I know if my sequence is too aggressive?
Signs of an overly aggressive sequence: reply rates are low but connection acceptance is adequate (meaning the problem is post-acceptance messaging); you start receiving "please stop messaging me" replies; LinkedIn sends your account a warning about automated activity. The primary cause is too many steps or too short delays. If you see these signals, reduce to 3 steps and increase delays to 5–7 days between each.
Can I pause a sequence for a specific prospect without pausing the entire campaign?
Yes. In Aimfox Unibox, find the specific prospect's conversation and look for options to pause or stop their sequence. This allows you to manage individual prospects (for example, a prospect you want to reach out to manually) without affecting the automated sequence running for the rest of the campaign audience.
How does Aimfox track which step each prospect is on?
Aimfox tracks the sequence state for each individual prospect in the campaign. You can typically view which step a prospect has reached by opening their record in the campaign view or in Unibox. The step tracker shows which steps have been sent, which are pending, and whether the prospect has replied or been marked as finished.
What happens to prospects who never respond to any step?
After step 4 (the final step) completes without a reply, Aimfox marks the prospect as finished in the sequence. No further automated messages are sent. You can then export these prospects for a 90-day re-engagement campaign, or simply leave them as finished records. Do not manually send additional messages to prospects who have been through a complete 4-step sequence without replying — they have had adequate opportunity to respond and are most likely not interested at this time.
Should I include links in LinkedIn follow-up messages?
Avoid links in steps 1 and 2. LinkedIn's algorithm is reported to deprioritise messages containing external links, and a link in early sequence steps can make the message feel more commercial and less genuine. In step 3 (the ask), a calendar link (Calendly, Cal.com) is generally acceptable and reduces friction for interested prospects. If including a link, use a shortened or branded version rather than a raw URL.
What reply rate should I expect from a well-configured 4-step sequence?
A well-configured 4-step sequence sending to a well-targeted audience typically produces a total reply rate (replies across all steps) of 8–15% of accepted connections. Step 1 produces the most replies (4–8%), step 2 next (3–6%), step 3 next (2–5%), and step 4 closes with the lowest rate (1–3%). Total sequence performance below 5% from accepted connections suggests either copy or audience issues that warrant investigation.
