Pre invite engagement: warming a prospect before the connection request
By Viktorio Shopov, co-founder of Sellinger. Reviewed by Asen Levov. Published . Last updated . 6 minute read.
Pre invite engagement means the sender likes, or comments on, a prospect's recent posts shortly before sending the connection request, so the name is not a stranger's when the invitation arrives. In Sellinger it is a setting on the LinkedIn agent: off until you switch it on, then two likes before each invitation by default (zero to five), and comments before the invite only if you turn them on. We have no campaign that isolates it, so we claim no gain.
This post explains the idea, what the setting does, and how to decide whether it belongs in your campaign without taking anyone's word for it, including ours.
What is pre invite engagement?
A connection request lands in a person's notifications with a name, a photo and, sometimes, a note. The person decides in a few seconds. The idea behind warming is simple: if the same name liked a post of theirs yesterday, the name may feel less random.
People do this by hand all the time. They follow a prospect, like a post, leave a short comment, then connect a day or two later. The manual version is slow, so it is usually used for a handful of key accounts. The agent version does the same steps for every lead queued for an invitation, within limits you set.
There are two separate things that sound alike:
- Warming the prospect. Likes or a comment on that person's posts before the invite. This is what the engagement setting does before an invitation.
- Warming the account. Ramping up the activity of a new LinkedIn account. Sellinger does not do this. There is no logic that ramps up a new account, and we say so on the product page.
How does it work in Sellinger?
Engagement is a setting on each LinkedIn account. It is off until you switch it on. Once it is on, two things can happen.
Before the invite. For a lead that is queued for an invitation and belongs to an active agent, the agent can like up to five of the person's recent posts and, if you choose, comment on one. The comment is written by the AI from your comment directions and the post itself. It runs from the same account that will send the invitation.
Topic comments. Separately, the agent can comment on posts about topics you list, up to a daily limit. The scan runs about every 30 minutes, looks through the feed for posts that match your keywords and records each match as an intent signal. It can also create leads from the authors of matching posts. That second mode is not about warming a specific prospect. It is a way to be present where your buyers talk, and a source of intent signals.
| Setting | Default | Range or note |
|---|---|---|
| Engagement, master switch | Off | Turns the feature on for the account |
| Likes before the invite | 2 | Zero to five |
| Comment before the invite | Off | AI written, follows your directions |
| Topic comments a day | 3 | Zero to ten |
| Delay between actions | 60 seconds | Ten to 600 seconds |
| Pause after refusals | 24 hours | After three refusals in a row |
Does it work?
We do not know, and we would rather say that than guess. Sellinger has no published campaign that separates engaged leads from non engaged ones, so we make no claim about acceptance or reply gains. The only numbers we hold on invitations are for the account as a whole: on our own LinkedIn outbound, 68,818 connection requests were sent and 41% were accepted, with engagement not a variable we tested.
Other tools sell warming as a growth trick. Without a controlled comparison, that is a claim and not evidence. The one thing we can say is mechanical: a like or a comment is a visible action, so it can only help if the person sees it and the action looks natural.
How would you test it?
A fair test is small and takes about a month.
- Pick one audience. Take a list of 400 people who match one description. Split it into two random halves of 200.
- Change one thing. Switch engagement on for the account that invites half A. Keep the other half invited from a comparable account without it. The invitation text and the sending days should match.
- Count one number. Count accepted invitations after two weeks and compare. Use the reply and acceptance rate calculator to keep the arithmetic honest.
- Look at replies too. Acceptance is not the goal. A warmer name that accepts and then does not answer is not a win.
With 200 people per half, a difference of a few points will not tell you anything. You are looking for a large gap, and if there is none, spare yourself the extra activity on the account.
What are the risks?
Every automated action on LinkedIn adds to the footprint of the account. Liking and commenting are no exception, and no tool can promise that LinkedIn will never restrict an account. That is why the feature has per action delays, daily limits and an automatic pause: if LinkedIn refuses the feature three times in a row, engagement stops for 24 hours instead of trying again.
Two practical rules help:
- Read the comments before you rely on them. The agent writes them from your directions. A generic "great post" is worse than nothing. Set directions such as "mention one specific point from the post, never promote our product".
- Start with likes only. Likes are quiet. Add comments later, on a small group, and read what is posted.
Our wider view of account safety is in the LinkedIn safety checklist for AI outreach. LinkedIn's own description of restrictions, which lists ignored and pending invitations among the reasons, is on its help page.
When does it make sense?
It fits when the list is small and specific, the people post regularly and a name that is slightly familiar helps: founders, consultants, heads of departments who are active on the platform. It fits less when the people rarely post, because there is nothing to like, or when volume is the goal.
It is a poor substitute for a good reason to write. On our own outbound the biggest differences came from who was on the list and what the first line said, not from the steps before the invitation. See observation openers beat questions.
A checklist
- [ ] I know whether I want to warm prospects or only be present in my topics.
- [ ] I start with two likes, comments off.
- [ ] I wrote comment directions that name something specific.
- [ ] I read the first comments the agent posted.
- [ ] I run a split test before I make it permanent.
- [ ] I accept that no tool can guarantee LinkedIn will never restrict an account.
Common questions
Does warming a prospect raise the acceptance rate?
Is this the same as warming up a LinkedIn account?
Will the agent comment on every prospect's post?
Can LinkedIn restrict an account for this?
