bt spam bot issues

having issues as of a few weeks ago that email that we sent to customers with bt email addresses often auto get rejected by the bt spam bot and the reason is simply, they suspect we could be spammers.

trouble is, if the only method of contact we have for the customer is the email, we now cannot get in touch. anyone know what we can do to help solve this issue? perhaps why we might be appearing as spam? the emails are typically plain text with a small signature with no photos

just a quick update. this is still an ongoing issue. have spoke with bt and they say must be the customers are blocking us, but it's impossible that every single bt customer blocks us before they even know our email address

checked spamhaus and not listed

oddly the email contact@domain is what gets instantly rejected, but accounts@domain is fine and gets through.

is just BT that does this. no other.

Yahoo are really strict when it comes to mass emails. If you try to send to more than, say a dozen addresses or more at a time Yahoo's filters will likely pick it out and suspect it's spam. The same with sending multiple emails, more than 20-30 in an hour. Again Spam or a compromised email account.

not something we've ever done. at most the customer might get 3 emails due to copies of the quotes being sent automatically and the booking request but that's it.

You're not the first person I've heard of having difficulties specifically with sending email from a contact@ email address to bt customers, and again, not the only person I've heard of saying that other email addresses on the same domain are fine. Makes me think that bt has developed a dislike for contact@

perhaps it is as simple as that. fml i just want to send emails. i think for now i will keep going with switching to the other email when they bounce back.

the issue has popped up once again. trying to send an email to vistaprint. have been replying back and forth for a few days until today auto rejected with the below:

"
[email protected]
host eu-smtp-inbound-1.mimecast.com [91.220.42.241]
SMTP error from remote mail server after RCPT TO:<[email protected]>:
550 csi.mimecast.org Poor Reputation Sender. - https://community.mimecast.com/docs/DOC-1369#550"

i've checked with vidahost who say our reputation is good, said something about them checking ptr record, or a dkim record and all was good, yet now every email we send vistaprint from any address is rejected instantly. so frustrating
