Tools!

I just added a DMARC validation tool over on tools.wordtothewise.com.

You can give it a domain – such as ebay.com – and it will fetch the DMARC record, then explain and validate it. Or you can paste the DMARC record you’re planning to publish into it,  to validate it before you go live.
If you’ve not seen our tools page before, take a look. As well as DMARC we have a DKIM validator, SPF expander and optimizer, general DNS lookup tools, a bunch of RFCs covering all sorts of protocols, and base64 and quoted-printable decoders.
There’s also a widget that lets you add those little unicode pictures to your subject lines, whether you need a snowman ⛄, a forest ????, or a pig getting closer ???.
The results pages all have easily copyable URLs so they’re pretty good for sharing with co-workers or customers if you need that sort of thing.
(And if you need a cidr calculator, whois, or easy access to abuse.net & Microsoft SNDS check out Al’s xnnd.com.)

Four things to check before your next mailing

Like many bits of technology, email is often set-and-forget. Everything is checked and rechecked during setup, and then no one goes back and looks at it again. But mail programs are not static, and people make changes. These changes don’t really break things, but over time they can create their own set of problems.
Setting aside some time every quarter or even every year to check and make sure all the bits of mail are configured correctly is a good idea.

Ask Laura: Can you help me understand no auth / no entry?

AskLaura_Heading3
Dear Laura,
I’m a little confused by the term “no auth / no entry”. Gmail and other major receivers seem to be moving towards requiring authentication before they’ll even consider delivery.
Does this just mean SPF and DKIM, or does this mean the much more stringent DMARC, as well?
Thanks,
No Shirt, No Shoes, No What Now?
