Common questions

Why do some Gmail readers get my issue the next day?
Gmail is careful with the first emails from a new domain. So on its first day, Wabimail sends an issue to its first 2,000 Gmail readers, and the others get it the next day. Readers on other inboxes get it right away, and a domain of your own you already send newsletters with isn't held back. Read more
Why did my campaign pause?
Too many of its emails bounced, were marked as spam or were refused by Gmail as unsolicited: more than 2.5% hard bounces (at least 5), 0.08% complaints (at least 2) or 2% Gmail refusals (at least 10). Emails already sent stay sent, and you can resume the rest from the campaign's page. Past 5% bounces or 0.3% complaints, the whole account is blocked. Read more
Why do new contacts get my issue in steps?
The first time you email contacts who never got an email from you, 2% of them go first, then 5% more 30 minutes later, then the rest 30 minutes after that, each step only if bounces, complaints and Gmail refusals stay low. A list with problems stops after a few hundred emails, before it reaches everyone. Read more
What happens to subscribers who stop opening?
With list cleanup on, a contact who ignored 6 issues in a row and showed no sign of life for 180 days gets one last-chance email instead of your issue. If they don't click it, they become dormant at your first send 14 days or more after it: they stay in your list, but stop getting issues and stop counting as subscribers. Read more
Can I unsend an email?
No. Emails can't be recalled once they go out. While a send is still going out, you can pause it: what's sent stays sent, and the rest waits until you resume. Read more
What counts as an email?
Every email Wabimail sends for you: issues, test emails, and welcome and confirmation emails. The count starts over every month, on the day your plan started. Read more
