Campaign Not Sending Invitations
What to check when participants aren't receiving their Signal Session invitations
When participants aren't receiving invitation emails, one of the following is almost always the cause. Work through these checks in order.
Check 1: What Status Is the Campaign In?
Open the campaign and look at its status badge.
- Launching — invitations are being sent right now. The campaign moves to Active once all invitations have gone out. Wait a few minutes and check again.
- Active — invitations have been sent. If participants say they haven't received anything, the issue is likely delivery (see Check 4).
- Scheduled — the campaign is launched but its start date is in the future. No invitations go out until that date arrives. To send sooner, adjust the start date.
- Paused — no new invitations are sent while the campaign is paused. Resume it from the campaign detail page.
- Draft — the campaign hasn't been launched yet. Launch it to begin.
Check 2: Is the Start Date Today or in the Past?
If the campaign is Scheduled, check its Schedule settings. A future start date means invitations go out automatically when that date arrives — not immediately. To send now, edit the start date and save.
Check 3: Is Your Balance Sufficient?
A campaign can't launch without enough funds to cover its reserved amount. If the campaign is stuck in Draft and won't launch, check Billing → Usage and confirm your balance covers the reserved amount. If it doesn't, add funds and launch again.
Check 4: Are Invitation Emails in Spam?
Ask affected participants to check their junk or spam folder — invitation emails from an unfamiliar sender often land there, especially for first-time participants. Ask them to mark it "Not spam" to improve future delivery.
Check 5: Are the Participant Email Addresses Correct?
From the campaign's participant list, check that every participant has a valid, correctly formatted email address (no spaces, no missing @, no .con typos). Invalid addresses are flagged during CSV import, but manually entered addresses can contain errors.
Check 6: Do You Need to Resend?
If a participant's invitation never arrived, you have two options from the participant list:
- Copy link — copy the participant's unique session link and send it directly by email, chat, or any other channel.
- Reset & resend — generate a fresh invitation and new session link for the participant. Use this when they had trouble with their original link.
Still Stuck?
If none of these resolve it, contact Savo support with your campaign ID (in the URL when viewing the campaign), the affected participant email addresses, and the campaign status at the time of the issue.
