If you receive an error which informs you that a message has been blocked due to spam content inside the email, this occurs because your email provider has decided that your email could potentially be spam - this is completely beyond our control, and unrelated to Mailbird.

However, we recommend trying to send that email directly from your webmail (e.g. Gmail, Yahoo, etc.) -  if you are not able to send it from your webmail, Mailbird will also not be able to send it.

The best way of solving this would be to reach out to your email provider regarding this issue, and to ask them to not consider your email account as suspicious, or likely to send spam emails.
