Can I send email from a domain without affecting existing users?

I have a client who has an existing domain name, for which they have a web site and email set up. They have asked me to do a new web site, and given me control over the domain name.

I would like to be able to send emails from the web site, using their domain name as the “From” address, but I don’t want to disturb whatever setup they already have for sending emails manually. I don’t know how they currently send emails, but given that their MX records are of the form, my guess is they use Gmail.

I want to use Amazon SES if it makes any difference.

Anyone able to advise? Thanks.

Yes, you can.

In fact, anyone can email from your domain but upon receiving many mail server will mark as spam if you didn’t configure an SPF record.

Here are step to send email with Amazon SES:

  1. Go to SES, add and verify your domain. They will ask you add a few CNAME/TXT record which don’t affect any thing on current domain.
  2. Setup SPF. Since the current domain already use gmail, so don’t overwrite the SPF TXT record but only insert Amazon record. Example: ` “v=spf1 ~all”

Notice how was inserted in the middle. Thanks for the reply.

  1. I already verified the domain, and added the TXT record.

  2. There isn’t an SPF record in there at the moment. Will I be safe adding one for, or do I need to include google, given that there isn’t one there now?

Thanks again.

Let’s do for both for + google one as well. Whoever set it up before didn’t do it. So it should like this "v=spf1 ~all"

Sorry to be dumb, but can you clarify this for me. Do you mean I add two SPF records, one with the name and one with the name, both with the content you showed, or did you mean one SPF record for both? If the latter, what do I specify for the record name?

Thanks again.

No, add a single TXT record like this in cloudflare
