There is a maximum amount of emails in single file that can be uploaded at one time. If you have a file larger than this it will require splitting. We also offer a Managed Bulk service for large files.
If you need help splitting the file, please request assistance using the form below and remember to attach a copy of the file.
You can upload multiple lists and just pay for the total amount of email addresses in all of the lists.
Unfortunately we currently do not allow any exceptions to this.
