Questions and answers about sending

Some addresses are marked as blocked when a newsletter is sent, even though they have never been actively blocked. What is the reason for this?

A blocking notice means that the recipient has expressed the wish not to receive any further newsletters from you. This can be done in the following ways:

  • Use of our unsubscribe form (or when testing the unsubscribe form - because it works!)
  • Click on the "Spam" button for participating providers (such as Yahoo, Hotmail, 1&1, GMX or others)
  • Use of the "Unsubscribe" function of programs such as Microsoft Outlook or Gmail.
  • Manual unsubscribe
  • Submitting an abuse complaint to us

A block can only be lifted by carrying out a double opt-in procedure or by our support.

Some addresses are marked as Unknown, even though we know that this address exists. How can this be fixed?

In principle, all addresses that are reported to us as 'unknown' by the receiving server are marked as 'invalid' and excluded from future mailings. We are obliged to do this because our IP addresses would quickly end up on the block list in the event of persistent delivery attempts to invalid email addresses.

If you are sure that an address exists despite the message, you can do the following:

  1. Open the report of the mailing
  2. Open the sending log
  3. Search for the address
  4. Click the question mark next to the sending description. This lets you reset the status and try sending again.

emails to internal addresses are marked as sent but do not arrive.

If you send internal emails, for example from ich@meinefirma.de to info@meinefirma.de, it may happen that these emails are recognized by our system as Delivered are marked but do not arrive.

This is normal behavior and not a fault of our service.

When delivering internal emails, it is normally assumed that there is a dial-in to the internal SMTP server (i.e. smtp.mycompany.com) with a user name and password, but this does not take place when our service is used to send emails.

It is therefore not uncommon for internal emails sent by external services to be classified as phishing emails and therefore not delivered. To resolve such a problem, please contact the administrator of the mail server responsible for your company emails.
