Can a reply to an ongoing email conversation land in spam?
Had an exchange of emails with someone, around 4-5 back and forth emails.
He then told me that my last reply never arrived. When I forwarded that email again to him, he told me that actually the original reply arrived but landed in spam... he checked it after I forwarded the initial reply.
It's not critical or even a super important conversation but I think he lied to me. Is there any chance that a reply lands in spam if the last 4 mails in a thread arrived without a problem?
The emails were sent from a custom domain, using Office 365 Business. I have that email address for more than 6 years and I never had a problem with my emails landing in spam or never arriving. It's the first time I am hearing about it but I think he is duping me.
Edit Thanks all for the replies, it's good to know that it can happen.
Wow! Thanks so much for the detailed response. I remember I tried mail-tester some time ago, I tried it now it gave me a 7.9/10
SpamAssassin. Score: -2.1.
-0.1 DKIM_SIGNED
Message has a DKIM or DK signature, not necessarily valid
This rule is automatically applied if your email contains a DKIM signature but other positive rules will also be added if your DKIM signature is valid. See immediately below.
0.1 DKIM_VALID
Message has at least one valid DKIM or DK signature
Great! Your signature is valid
-0.001 HTML_MESSAGE
HTML included in message
No worry, that's expected if you send HTML emails
sender matches SPF record
Great! Your SPF is valid
This is the other part of the test with yellow checkmarks.
You're not fully authenticated
[SPF] Your server xx.xxx.xx.xx is authorized to use mail@xxxxx
Your DKIM signature is valid
You do not have a DMARC record
You do not have a DMARC record, please add a TXT record to your domain _dmarc.xxxx with the following value:
v=DMARC1; p=none
Your reverse DNS does not match with your sending domain.
The rest seems to be green except for the List-Unsubscribe header but I do not send newsletters.
Thanks so much! Well after a few days, I think that person lied to me and I don't think anything landed in his spam. I think it was his way of getting out of something.
Anyway should I also go ahead and do a DMARC record or is SPF and DKIM enough?
Wow this is invaluable, I would love to do that and contact you. I am in a busy period so that's why it took longer to respond. I will most likely make the changes in 1-2 weeks. Is it ok if I DM you in 2 weeks or whenever I made the changes? Thanks!
