How to Automate LinkedIn Follow-Up Messages
An automated follow-up only works if it gives someone who ignored the first message a genuinely new reason to reply. Two follow-ups, three at most, three to five days apart, 20 to 40 words each, a different style every time, and each one shorter than the last. Every follow-up hangs off the no-reply branch, so anyone who answers drops out of the chain automatically.
Run it when: after the first message is written. Never before, because a follow-up is defined by what came before it.
Time: 20 minutes for both.

How to write and automate LinkedIn follow-ups
1. Understand what a follow-up actually is.
They saw the first message. They did not reply. A reminder is not a new reason to reply. Every follow-up must carry a new angle, a new piece of value, or a new question. If it repeats the first message in other words, it is noise.
In Reachium each follow-up hangs off the previous message's no-reply branch, so the moment somebody answers, the rest of the chain stops by itself. You never chase a person who already replied.
2. Send it three to five days later.
Sooner reads as pressure, later reads as a different conversation. Three to five days is the window.
3. Write two follow-ups. Three is the ceiling.
One or two is the default and covers most of the gain. A third is allowed if you really want the full chain. There is no fourth.
4. Keep the format exact.
Two lines, blank line between, one sentence each, 20 to 40 words total, and always shorter than the first message. The chain should get lighter as it goes, not heavier.
5. Pick a different style for each one.
Five that work:
Continuation: "And {{first_name}}, ..." picks up mid-thought like a second idea you just had.
Warm restart: "Hey {{first_name}}, ..." casual reopen with a new angle.
Curiosity hook: "Quick question {{first_name}}, ..." opens a gap they want closed.
Value drop: "{{first_name}}, we just put together..." leads with something free.
Forgot to mention: frames it as an afterthought rather than a pursuit.
Use a different one in each follow-up, so the chain does not read as one script running.
6. Never use the following-up words.
"Just following up", "circling back", "bumping this to the top of your inbox", "checking in". These announce that the message contains nothing new, which is usually true when someone reaches for them. Rewrite with an actual reason.
7. Give the CTA two doors.
One easy, one slightly bigger: send the resource, or take 15 minutes. People who will not book a call will often say yes to a document, and that reply starts the conversation anyway.
8. Still no links.
The value drop style offers the resource. It does not attach it. The link goes out after they reply.
The shape
{{first_name}}, we just put together a breakdown of [the thing you actually made, and what it produced].

Do this | Not this |
|---|---|
A new angle in every message | "Just following up on my last note" |
20 to 40 words | A longer message than the first one |
A different style per follow-up | The same opener three times |
Two options in the CTA | One calendar link |
Three to five days apart | Next-day chasing |
Stop at two, three at most | A five-message chain |
Offer the resource | Paste the resource link |
Questions people ask
How many LinkedIn follow-ups should I send?
Two is the default and covers most of the gain. Three is the ceiling. There is no fourth. Each one has to carry a new angle, a new piece of value or a new question. A reminder is not a reason to reply.
How long should I wait between LinkedIn follow-ups?
Three to five days for the first, five to seven for the second, seven or more for a third. Sooner than three days reads as pressure; much later reads as a different conversation altogether.
Can you automate LinkedIn messages?
Yes. Each follow-up hangs off the previous message's no-reply branch, so the chain runs on its own and stops the moment someone answers. You never chase a person who already replied.
What should I not say in a follow-up?
"Just following up", "circling back", "bumping this to the top of your inbox", "checking in". Each announces that the message contains nothing new, which is usually true when someone reaches for them.
