What bounce rate suspends a Brevo account?

Brevo lists a hard bounce rate above 2%, an unsubscribe rate above 1% and a complaint rate above 0.2% as suspension triggers.

Why was my Brevo campaign to new contacts suspended?

Brevo samples campaigns sent to new contacts and suspends them when engagement looks poor within 1 to 3 hours. Verifying the new contacts first removes the bounces that drag those numbers down.

Does RocketVerifier blocklist contacts in Brevo?

Yes, if you turn it on. Undeliverable addresses are added to the Brevo blocklist and results are written to contact attributes.

How much does it cost?

1 credit per address, with unknown results and duplicates free and pay-as-you-go credits that never expire. New accounts start with 100 free credits.

How to clean a Brevo contact list

Quick answer

To clean a Brevo list, connect Brevo to RocketVerifier, verify all contacts or a list, write the results to contact attributes and blocklist undeliverable addresses. Brevo can suspend campaigns and the account when hard bounces pass 2%, unsubscribes 1% or complaints 0.2%, and it samples campaigns to new contacts within 1 to 3 hours. Verify every new batch before its first campaign.

How Brevo handles bounces and imports

Hard-bounced addresses are blocklisted automatically.
A campaign address that soft bounces five times in a row is blocklisted. Deferred mail is retried for 36 hours before it counts as a soft bounce.
Scraped, acquired or purchased lists conflict with Brevo's anti-spam policy.
After a suspension, Brevo asks you to clean the database before reactivation, and a repeat suspension can lead to deactivation.

Tips for Brevo

Verify every new import before its first campaign. That first send is the one Brevo samples.
Keep a list of only deliverable and send_safe contacts for new-contact campaigns.
If a campaign was suspended, verify the new-contacts segment Brevo provides and remove what fails before you ask for reactivation.
