LinkedIn Seat Fees (Monthly)
Seat fees apply to the Messaging API only — specifically when you connect LinkedIn accounts for automated outreach. Each connected LinkedIn account counts as one seat. If you are only using the Identification API (ip-to-company, ip-to-best-fit, visitor listing), seat fees do not apply.
Seat fees are billed at the end of each billing cycle based on the maximum number of seats connected at any point during that cycle. On the Free tier, 1 seat is included at no cost.
| Connected Accounts | Price |
|---|---|
| 1–10 | £55 flat |
| 11–50 | £5.50 per account |
| 51–200 | £5.00 per account |
| 201–1,000 | £4.50 per account |
| 1,001–5,000 | £4.00 per account |
| 5,001+ | £3.50 per account |
Auto-Reload
Never run out of credits mid-campaign. Set an auto-reload threshold in your billing settings at platform.warmai.uk/billing . When your balance drops below the threshold, credits are automatically purchased using your payment method on file.
