Whenever you replace your DNS supplier with a DNS file supplied by SendGrid, after which ship mail over your IP, the recipient’s e-mail service supplier performs a reverse DNS lookup (rDNS) utilizing an A File (deal with file).
An A File maps your area to your IP deal with. When a mailbox supplier appears up your A File, they see your SendGrid IP deal with.

What ought to I do? We’ve got step-by-step instructions to arrange reverse DNS in your sending IP deal with.
3. Maintain spam charges reported in Postmaster Instruments under 0.3%.
What does it imply? Senders might want to preserve their spam criticism price under 0.3% in Google Postmaster.

What does it imply? RFC 5322 is an Web normal that defines the right format for e-mail messages. That covers the message headers, physique, and attachments.
What ought to I do? SendGrid already blocks emails from deploying that don’t observe RFC 5322 compliance tips, similar to if a ‘from header’ isn’t included. Look by way of the Web Messaging Format and make sure every part (envelope, physique, header, and attachments) meets the necessities.
5. Don’t impersonate Gmail From: headers.
What does it imply? Gmail will start to make the most of a DMARC coverage of ‘quarantine.’Should you try to impersonate a Gmail From: header, that may doubtless impression your e-mail supply.
What ought to I do? This one is kind of easy. Don’t impersonate a Gmail From: header. In a nutshell, don’t ship from ‘instance@gmail.com’.
6. Should you recurrently ahead e-mail (together with utilizing mailing lists or inbound gateways), add ARC headers to outgoing e-mail.
What does it imply? As Google helps clarify of their weblog publish, ARC verifies earlier authentication checks for forwarded messages and helps guarantee forwarded messages are delivered to the ultimate recipients.
How are you aware in case your mail is being forwarded? Your mail is being forwarded in case you ship to mailing listing companies that ahead messages onto remaining vacation spot inboxes or inbound gateways. It’s essential to not confuse list-serv forwarding with a person recipient forwarding an e-mail from their inbox. Checklist forwarding or Checklist Serving is a particular routing problem addressed by ARC.

7. Arrange DMARC e-mail authentication in your sending area.
What does it imply? DMARC (Area-based Message Authentication, Reporting & Conformance) is a typical that builds on SPF and DKIM. DMARC communicates a coverage to mailbox suppliers letting them know what they need to do once they obtain an e-mail that fails an SPF, DKIM, or SPF and DKIM examine purporting to be out of your area (presumably spoofed).
What ought to I do? Should you don’t have already got a DMARC file in place, you’ll need so as to add one to your DNS. Should you’re unsure if you have already got DMARC in place, you possibly can examine by way of Valimail at no cost.
Listed below are the steps to implement DMARC:
- Go to your DNS internet hosting supplier and create a file.
- Choose TXT DNS file sort.
- Add the host worth ‘_DMARC’. In case your DNS supplier doesn’t robotically append your area title, alter the host worth to incorporate your area ‘_dmarc.area.com’.
- Create your DMARC file and add it to the DNS TXT worth. A easy DMARC file ought to seem like: ‘v=DMARC1; p=none; rua=mailto:dmarc_agg@vali.e-mail’. The rua tag is used to outline the place the DMARC reviews must be despatched. Included in our instance DMARC file is Valimail’s monitoring deal with, as they supply free monitoring.
- Hit the save/ submit/ submit button and confirm your DMARC file has been added accurately to your DNS.
Every DMARC file must outline a coverage, which may be one among three choices: none, quarantine, or reject. Though Gmail’s requirement for DMARC is to set it at p=none, it is a minimal bar. P=none instructs the receiving mailbox supplier to take no motion on an e-mail that fails an SPF/DKIM examine.
The most effective, and most safe setting, is what’s known as DMARC at enforcement, p=reject or p=quarantine. Nevertheless, this requires extra work to make sure that this file incorporates the entire third events sending on behalf of your area. Publishing the file incorrectly may trigger your mail from these suppliers to not be delivered. Work together with your technical personnel to make sure that your DMARC is correctly formatted and affords you the best degree of safety.
8. For junk mail, the area within the sender’s From: header have to be aligned with both the SPF area or the DKIM area.

Alignment refers to the verification that the DKIM and SPF signatures in your e-mail headers align with the area you’ve authenticated your SendGrid account with.
What ought to I do? In a simplified reply, that you must make sure the “from” deal with you might be specifying within the “From: header” matches the area you authenticated with SPF or DKIM. Past the simplified reply, there’s strict alignment and relaxed alignment and a number of other situations (together with the usage of subdomains) that you must contemplate. Fortunately, Google has a whole weblog publish on explaining these situations in nice element.
9. For subscribed messages, allow one-click unsubscribe and embrace a clearly seen unsubscribe hyperlink within the message physique. Study extra
What does it imply? One-click unsubscribe (listing unsubscribe) offers a second methodology for subscribers to simply take away themselves out of your mailing listing. The Checklist-Unsubscribe header will insert an “unsubscribe” button, or hyperlink, subsequent to the From deal with on the prime of your e-mail.
What ought to I do?
