Deliverability
Unsubscribes and bounces
Unsubscribe — the footer link opens a confirmation page in the campaign language. The "Unsubscribe" button of Gmail and Yahoo (one-click unsubscribe) works too. The customer loses their newsletter subscription in PrestaShop and joins the Unsubscribes and bounces list; if they subscribe again from their account or the newsletter form, they leave it automatically.
Bounces when sending — an address refused by the SMTP server (non-existent mailbox) is removed from all sending right away.
Bounces after sending — the Bounce handling tab offers two ways:
- IMAP mailbox: set a dedicated return address; the scheduled task reads its mailbox at most every fifteen minutes. Permanent non-delivery reports and spam complaints remove the address from sending; temporary bounces (mailbox full) are ignored; other messages in the mailbox are left untouched.
- Webhook: with Brevo, Mailjet or Amazon SES, declare the displayed URL with the provider; permanent bounces, complaints and unsubscribes arrive directly.
Manual list — the Unsubscribes and bounces tab also lets you add addresses by hand or remove an address from the list.
