[BETA] Why not delete contacts who are blocklisted?

In this article, we will explain why we recommend keeping your blaoklisted contacts instead of deleting them from your Sendinblue account.

Should I blocklist or delete contacts?

Regarding deleting or blocklisting your contacts, you can choose to do either. However, we recommend you leave the contact as blocklisted in your account to protect the quality of your campaigns.

Why not delete contacts who are blocklisted?

Keeping blocklisted contacts ensures that you cannot accidentally re-import and send campaigns to contacts that are found to be invalid, or to those who have previously opted out of your communications.

If you end up keeping the blocklisted contacts, we recommend you create a separate contact list

To do so, you can segment your blocklisted contacts, then create a list from these blocklisted contacts. 

  1. Go to Contacts.
  2. Click + Add a condition .
  3. In the drop-down menu, select Subscription status> Email, SMS, or WhatsApp  > Blocklisted and click Validate this condition.
  4. Select all your blocklisted contacts. 
  5. Click Add to a list(s)
  6. Add your blocklisted contacts to a new list, for example, a new list named "Blocklisted contacts". 
    To learn how to add segmented contacts to a new list, check our dedicated article Create a list from an existing contact list.
💡 Good to know
If a contact was blocklisted by error or if they asked to be subscribed again, check out our dedicated article to learn Remove a contact from your blocklist.

Can blocklisted contacts still receive emails?

In Sendinblue, email campaigns and transactional emails have two separate blocklists. This means that if a contact is blocklisted from receiving your email campaigns, they can still receive your transactional emails. To be blocklisted from both email campaigns and transactional emails, the contact would have to unsubscribe/mark as spam both an email campaign and a transactional email.

❗️ Important
When a contact unsubscribes from a transactional email, they are only blocklisted from the sender of this specific email. They can still receive transactional emails sent from another sender.
For example, if a contact unsubscribes from the transactional emails sent from, they can still receive emails sent from
