Error statuses in campaigns:
  • does not exist;
  • unavailable;
  • full.

In the "SMTP Response" column, you can see codes and error descriptions to resolve them yourself for successful email sending.

If you receive errors (e.g., bans) from email services such as Mail.ru, Gmail, and Yandex, then most likely your domain has been added to a spam filter, and you need to warm up the domain. Email systems are suspicious of a large volume of emails sent from an unwarmed domain and may send your campaign to spam, and some will reject it at a technical level and block the domain.

If you cannot understand the reasons for suspicious metrics, contact our support, we will help you.
