After literally MONTHS of fighting with yahoo, I have found a business email-hosting solution that (so far!) is outstanding.  MailTrust ranks top of the list on customer service - from the Live Chat guy to everyone on their customer support team ( I think I’ve met them all!). Super quick to respond, courteous and they go above and beyond what I would expect of a company with ‘good’ customer service.

They guarantee 100% uptime - so far so good.

They also have broadcasting capabilities, so it doesn’t look like I’ll get tagged as a spammer (for some reason, Yahoo didn’t like my 16,000+ sent emails - even though they were all sent to individual clients/ inquiries with at most 2-3 CCs).

I’ll keep you posted,  but two thumbs up for Mail Trust.
