How bounce protection keeps your email accounts safe
Swyftreach pauses a campaign when 5 emails in a row bounce, holds it for 12 hours and alerts you. Learn how it works, what to fix, and how to resume safely.
A bounce is an email that couldn't be delivered, usually because the address doesn't exist. A few bounces are normal. A run of them tells Gmail and Outlook that you're mailing a bad list, and they start sending your future emails, even good ones, to spam. Bounce protection stops that from happening while you're not watching, including overnight.
How it works
- Every time an email bounces, Swyftreach looks at the campaign's last 5 sends.
- If all 5 bounced, the campaign is paused straight away and nothing else goes out.
- The campaign goes on a 12-hour safety hold. During the hold it can't be resumed.
- You get an in-app notification and an email, and the campaign page shows a red banner with a countdown.
What counts as "in a row"
- Sends are checked in the order they went out, so bounces that come back a few minutes late still count.
- One good delivery breaks the run. Five bounces spread between successful sends won't pause the campaign.
- Temporary failures, such as a full mailbox or a busy server, don't count until they repeat enough to become a real bounce.
- Addresses already on the bounce list are skipped before sending, so they never reach a mailbox and don't count.
Use the hold to fix the cause
- Clean the contact list: remove old, guessed or role addresses (info@, sales@) and verify the list if you bought or scraped it. Bounced contacts are already excluded from future sends.
- Check the sending account: open Email Accounts and make sure it's still connected and hasn't been blocked or suspended by its provider.
- Run a Spam Score check to confirm SPF, DKIM and DMARC are in place and your domain isn't blacklisted.
- You can edit the campaign during the hold, including its lists and senders.
Resume after the hold
- Wait for the 12-hour hold to end. The Resume button shows the time left and unlocks on its own.
- Choose Resume (or Save & resume in the editor).
- Type continue in the confirmation box and confirm.
Protection starts counting again from zero when you resume, so bounces from before the pause can't trigger it a second time. If the next 5 sends bounce too, it pauses again with a fresh 12-hour hold.
