Limits and deliverability
The daily and weekly ceilings, the acceptance rate we stop at, and why a launch is deliberately not instant.
Last reviewed September 8, 2026
Every limit here is a ceiling on your account, not ours. That framing matters: if LinkedIn restricts a profile or a mailbox lands in spam, it is your name and your network that carry it, and there is nothing we can undo for you afterwards.
The daily ceilings
Per connected account, per day:
| Action | Limit |
|---|---|
| Emails | 40 / day |
| LinkedIn messages | 40 / day |
| LinkedIn connection requests | 20 / day · 90 / 7 days |
| Withdrawing connection requests | 20 / day |
If a limit is reached, the rest of the queue moves to the next day. Nothing is lost and nothing is dropped.
Why the weekly invitation number is the one to watch
LinkedIn allows roughly 100 invitations per rolling seven days — on free, Premium and Sales Navigator alike — and an account that goes past it gets restricted. We cap at 90 rather than 100, because the last ten are not worth the risk.
We also watch your acceptance rate. If too few of your invitations are being accepted — under 15%, measured only over invites old enough to have been answered — we stop sending them and tell you. A low acceptance rate is exactly the signal LinkedIn uses to decide an account is spamming, and stopping is cheaper than being restricted.
Pacing, not bursting
Two mechanisms keep a launch from looking like a machine.
Steps are spaced. Even with no delay between two steps, the second lands a few minutes after the first.
Sends are staggered across leads. Launching to 200 people does not send 200 emails at once; they are spread across your sending window. This is the single biggest thing protecting your domain reputation — and it is why a launch does not look instant, which is the point.
By default the window is Monday to Friday, 08:00–18:00 in your timezone. Anything that comes due outside it waits for the next window rather than sending at 03:00.
Unaccepted invitations are withdrawn for you
LinkedIn reduces an account's sending capacity as its outstanding invitations pile up. An invitation nobody answered after 21 days is withdrawn automatically, which costs nothing — withdrawing does not affect your standing — and keeps that pile from growing.
What arrives under every email
The signature can be switched off per step; two things cannot.
- An unsubscribe link. One click, and the person is added to your do-not-contact list across every outreach you run.
- Your postal address. US commercial email must carry one, assessed per message rather than per campaign. It is a legal requirement, not a preference — which is why Review warns when the signature has no address on it.
