Yes, it is enews-letsengage.com, apologies for the typo. Could be tricky on the uniformbenefits.com spf as we tried to set up the newseltter sender on the subdomain news4.uniformbenefits.com so that it could all be configured separately from the main domain which is used for sending regular mail such as replies to support etc. I will look into this to see how that can be resolved.

Having never had a need to diagnose and fix deliverability trouble as (apparently) mysterious as yours, I'll stick to some visible problems which may be contributing and hope others who work more on the bulk sending side can provide deeper aid...

If you actually use that domain in email, particularly as the SMTP sender domain, you will have severe problems. However, if your reference to enews.letsengage.com was just a typo for enews-letsengage.com, the DNS for this domain is a non-problem. > Looking at best practice we saw that we really should be sending from > our > website domain (uniformbenefits.com) and not a separate domain which > is > associated with our company name (Let's Engage limited).

You have 1 more SPF TXT record than is useful for uniformbenefits.com: $ dig uniformbenefits.com txt |grep spf uniformbenefits.com. 14400 IN TXT "v=spf1 ip4:91.232.125.63 ip4:91.232.124.108 +a +mx ~all" uniformbenefits.com. 14400 IN TXT "v=spf1 include:spf.sendinblue.com mx ~all" This means you effectively have *NO* SPF record, as there's no standard mechanism to use or combine multiple records for the same domain name. It is always wise to get an impartial 3rd party evaluation of your SPF record when sending mail in bulk, because it is a factor used in nearly every spam abatement system. As SPF validation is simple to do, there are free tools for it. I like https://www.kitterman.com/spf/validate.html because it provides multiple test modes and is (as far as I've seen) both correct and complete. -- Bill Cole b...@scconsult.com or billc...@apache.org (AKA @grumpybozo and many *@billmail.scconsult.com addresses) Available For Hire: https://linkedin.com/in/billcole _______________________________________________ mailop mailing list mailop@mailop.org https://chilli.nosignal.org/cgi-bin/mailman/listinfo/mailop --- This email has been checked for viruses by AVG. https://www.avg.com _______________________________________________ mailop mailing list mailop@mailop.org https://chilli.nosignal.org/cgi-bin/mailman/listinfo/mailop
