When I send a mailing out it is only being delivered to I think around 50% of the contacts it should be. I am not receiving them despite being on the mailing list and others I have asked. However, when I click on the report it is saying it has successfully delivered to all contacts. I assume it is around 50% as my clicks are down 50% compared to 2 weeks ago.

  • can you compare before and after and see if it particular mailing platforms that are affected
