Why am I blocked from sending emails?
Qomon uses Brevo’s infrastructure to send campaigns and targeted emails.
If your sending is suspended, it means an issue was detected with your account.
👉 You can check the exact reason directly in your Communications tab (Email campaigns > Select campaign name > “Your campaign in numbers”).
📉 Why suspensions happen
To ensure good deliverability (with Gmail, Outlook, etc.), the performance of your campaigns are monitored. Your account may be suspended if:
Campaigns show poor results (recent sends or tests on new contacts)
High negative metrics are detected:
Hard bounce rate > 2%
Unsubscribe rate > 1%
Complaint rate > 0.2%
Transactional (targeted) emails have poor performance
Your account was compromised
You breached the Terms of Use
🟢 How to reactivate my account
If blocked on campaigns
First suspension: contact the Qomon Support team.
Clean your contact list:
In Qomon: Identify bounces/unverified emails and remove the emails from the contact card or add a tag (e.g. “Invalid email”) so you can exclude them from future sends.
Or via import:
Export the campaign contact list (Contacts > Advanced filters > Email Campaigns > Campaign name = “xx”).
Verify invalid emails externally (with a validation tool or manually).
Reimport the cleaned file into Qomon with Qomon ID.
Tag invalid addresses (e.g. “Invalid sender”) so you can exclude them future emails.
Check your DNS configuration: make sure your SPF, DKIM, and DMARC records are set correctly.

Note: If your account is suspended a second time, it cannot be revalidated!
If blocked on transactional emails
Simply contact Qomon Support.
Our team will review the quality of your transactional emails and restore sending if everything is in order.
