Hello, we've been having problems properly inboxing when mailing a customer list of ours. Using Sendgrid with Interspire resulted in our mails ending up in the spam filter and them temporarily blocking our account. So we need a better solution. Looking at about 100k emails/week. Please PM me your suggestion, fees and skype and I'll get in touch. IMPORTANT: You should have some sort of track record on here that hopefully doesn't include a place in the shitlist. We're not on a budget but we want to work with pros and not be scammed over $100.
