It may happen to deal with big mailing lists that contain duplicate addresses.
Don’t worry! SendBlaster automatically searches for duplicates and fixes them.
And no action is required! Duplicates in the same mailing list are automatically filtered out when sending, even if you have disabled the Don’t add addresses when duplicated or already present in the list option during your import operations.
We consider it an extremely effective and hassle-free tool. You’ll never annoy your recipients with doubles and, of course, you may improve the performance of your campaigns…instantly!
