Email sent to an alias is not delivered

In the event that SimpleLogin can't deliver an email to your mailbox, we'll:

  • create a notification and
  • send you an email to inform you about the issue

You can then download the email that can't be delivered.

Please note that an email sent from a mailbox to its own alias isn't delivered: the email is just dropped by SimpleLogin. The reason is that this could form a loop and have a side effect on the reverse alias system.

Emails end up in Spam

In the event that SimpleLogin emails are put into the Spam folder, you can create email filters to explicitly allow emails from SimpleLogin.

SimpleLogin never sends spam and no one can spoof SimpleLogin emails thanks to SPF, DKIM, and DMARC protection. We take it a step further by creating an anti-phishing program to detect potential phishing attempts.

However, some email providers might mistakenly put SimpleLogin emails into Spam or Junk folders, especially when you start receiving emails from SimpleLogin. To mark SimpleLogin as a safe sender, please create a filter for emails sent from or domains.

And please do not put SimpleLogin emails into Spam, as this is harmful to our email delivery reputation. Instead, if you start receiving spam sent to your alias, you can either:

  • disable the alias or
  • block the sender
