The emails that I am sending are ending up in receiver's spam

[Sam35]

My clients are calling me to tell that my conversations are ending up in their spam email. But I have had conversations with them in the past but that was never the issue its only now that is happening. There are no such content or words in the email that could trigger spam settings.

Could any one help me with that?

Hello, sometimes it is automatic - ask people who have your emails in the garbage to add your address to trusted senders - this should solve the problem :)

Hi @A1,

I have emailed them a couple of times already. it never occurred before.  There was a security breach couple of days earlier so the company had to tighten security. Can that be a reason?
