A 'failed' delivery can have several reasons. One reason could be that in the time between choosing the recipient and actually sending of the mail, the recipient has unsubscribed from your mailings. This can be checked by looking up the recipient in the contact list. If the contact has a stop icon next to the envelope, then this contact has unsubscribed from your mailing. You can therefore no longer send them an email. Various other reasons could be:
The recipient's inbox is full
A too 'strict' spam filter makes that mailings do not arrive or end up in the Spam, Promotion or Junk folders
Your internet connection is not working, or is slow
There are too many (heavy) software programs running on your computer, which delays transmission and/or reception
If you see that a certain contact does not receive mailings time after time, you should check whether the email address is still in use. If it concerns a contact from the Journalist database, we would like to hear from you! You can pass on your feedback via the Feedback button on the contact in Smart.pr, support@smart.pr, or the chat.
