DKIM authentication for gmail

[Vazken]

I am trying to authenticate our Gmail in Google workspace but when I create a TXT record in Shopify's domain DNS settings I'm getting "Value is too long" to copy the TXT value from Google.

Can someone help please?

Thank you

Hey @Vazken,

Welcome to the Community!

The "value is too long" error typically occurs when the TXT record value you are trying to add in the DNS settings exceeds the maximum character limit allowed by Shopify.

Google seems to automatically create DKIM records in 2048 bit, which Shopify does not support. If you ask to generate a new DKIM record, Google asks you if you want this to be in 1024 or 2048 bit. If you choose 1024 bit, Shopify has no problem accepting your new TXT record. Your email should then authenticate in google workspace with no trouble.

It's nice to see that you have set up a custom email address! It's such a great way to allow your business to appear more professional, as well as to strengthen trust with prospective customers. If you're looking to continue to build your business' brand imagery, I recommend going through our resources linked below:

Hey Moira! So what is the solution if I would like to add a 2048 bit DKIM record? Does Shopify have any plans to support 2048 bit DKIM records? It would be great if 2048 bit records are supported considering the increased level of security it offers compared to the conventional 1024 bit DKIM records.

I will reach out to our internal technical team and follow up once I receive a response!

Any update on this, Moira?

Moira, we will need a 2048 bit DKIM record otherwise Google is marking emails as spam. This is very urgent.
