How InMail delivery is verified
When WarmySender sends a LinkedIn InMail on your behalf, every successful send is verified against our LinkedIn provider's response before any counter or dashboard tile is incremented. This guide explains how that verification works and what you should expect to see on the dashboard.
How it works
LinkedIn InMail is an off-network message that goes through the recipient's LinkedIn inbox even if you're not connected. WarmySender drives LinkedIn actions through a specialist integration partner, and creating an InMail goes through them. On a real send, LinkedIn hands back a conversation ID — the unique identifier of the InMail thread on LinkedIn's side. WarmySender treats the presence of that conversation ID as proof of delivery: no conversation ID means the InMail did not actually queue on LinkedIn, even if the send request itself came back looking successful.
This matters because LinkedIn rejects InMail sends for several legitimate reasons: the recipient might not be eligible (no Open Profile, no Sales Navigator credits, account paused), the daily / weekly cap might be reached, the network might have hiccupped, or the underlying LinkedIn session might need a refresh. In any of these cases, the send request can come back looking successful while the InMail itself was silently dropped. WarmySender's contract with you is that the dashboard counter and the per-account InMails-Sent-Today tile only advance when the conversation ID proves the message landed.
What you'll see on the dashboard
- InMails Sent — Counts only verified sends. If you see this counter at zero while your campaign is active, it means we attempted the send but LinkedIn never confirmed a conversation. Check the Account → Health tile for cap exhaustion or eligibility issues, and check the campaign's most-recent skipped events for the specific reason.
- InMail Replies — Counts only inbound messages on a verified thread. Reply rate is computed against verified sends, not attempted sends — your reply % is honest.
What to do if your InMail count looks lower than expected
1. Check the campaign's per-prospect skipped events. If many say the InMail was never confirmed, the underlying account or eligibility check is failing — review your LinkedIn account's Sales Navigator subscription status, InMail credits remaining, and the recipient's Open Profile flag (if applicable).
2. Check your account's daily InMail cap on the LinkedIn Accounts page. WarmySender ramps InMail caps over the first 4 weeks in line with our integration partner's account-safety guidance.
3. If counts look right but your delivery rate is unusual, contact support — we'll pull the delivery trail for your account and confirm what LinkedIn returned on each attempt.
Why we don't count phantom sends
A platform that counts every attempted send, confirmed or not, as a successful send produces an inflated dashboard, an incorrect cost-per-reply ratio, and a false sense of throughput. Worse, when a customer pays for Sales Navigator credits, they're entitled to know which credits were actually consumed and which were silently dropped. We treat InMail sends like financial transactions: no confirmed conversation, no count.
