Why are my emails not being delivered.

Support Team

Last Update vor einem Jahr

If you are experiencing emails not being delivered it is most likely due to the fact that you are reaching the emial service provider limits.  All email service providers place limits on how many emails you can send daily and have a limit to how many recipients you can have per email.  Look up what the limits are for your email service provider. Even if you are within your limits there are many variables to email marketing such as the subject line, content, etc.  If the email message appears and reads like spam you are more likely to have your emails land in the spam box or not be delivered.  We also recommend that you check to make sure your domain/email address is not on the blacklist.
