AWS has good IP reputation - I’ve got one client sending <500K a month and one sending >20M a day off AWS and their IP rep at google is all in the green. Mailgun/Sinch are one a lot of my clients are moving to, as well. There’s also whatever-they’re-called-now-but-used-to-be-Sparkpost.
I’m really unsure that email is a good way to do this kind of contact, though. It’s too easy for the actual recipients (whether they’re the actual debtor or not) to affect your reputation. laura > On 25 Mar 2024, at 21:52, Michael Irvine via mailop <mailop@mailop.org> wrote: > > Thank you everyone.
