Deliverability: bounces, unsubscribes and spam

Some invitations never arrive, and that's normal for any bulk email. What matters is how the failures are handled and what you do about your list afterward.

What happens to bad addresses

When an address hard bounces, meaning the mailbox doesn't exist or can't accept mail, or a recipient marks an invitation as spam, that address is automatically added to a do-not-send list. Future sends, from any of your charts, skip it. This protects your account's reputation, not just that one recipient.

Guests can opt out

Every invitation includes a way for the recipient to unsubscribe. If a guest does, their address joins the same do-not-send list and they won't receive further invitations from you, across all your events.

When sending gets paused

If too many of your emails bounce or get marked as spam in a short period, your bulk sending can be paused temporarily to protect deliverability for you and for everyone else sending through SeatPlanning. If this happens, you'll get an email explaining why and what to check. Reply to that email or contact support to have sending restored.

Keep your list healthy

• Double check addresses guests give you, especially ones typed by hand rather than imported.
• Fix obvious typos on your guest list before you send, rather than after something bounces.
• Avoid importing old lists or contacts who haven't heard from you about this specific event. Invitations work best when the recipient is expecting one.
• If someone tells you they're not getting your emails, check their address on the guest list first. A small typo is the most common cause.

Where to go next

• Send email invitations for the sending flow this protects.
• Email sending allowances to understand your account's sending caps.
• Track responses and filter your guest list to spot guests who haven't responded.
