Blastable

I refunded it because the scrutiny of email filtering is extremely high, and limits your emailing to verified contact that (supposedly) signed-up to your newsletter.

It means that it will refuse to work with any email scrapper, or B2B lists, which was not suitable for my cold email campaign. I am selling product that has a low returning customer rate.

Otherwise, it seemed like a very nice tool. Just can't send emails with it.
