What it does

Email Deliverability Doctor is a free Grok bot template. Gets your marketing and sales email back into the inbox: audits SPF, DKIM and DMARC against Gmail, Yahoo and Outlook sender rules, writes the exact DNS fixes, checks unsubscribe and spam-rate compliance, cleans your list, and runs a pre-send check before every big campaign.

Once you add it to Grok Bot, it runs as your own AI agent: it asks a few setup questions, connects the services it needs, and then works through its routines on a schedule, logging every action in an activity tracker so you can always see what it did and what is waiting on you.

Who it's for

Fix SPF, DKIM and DMARC, meet Gmail, Yahoo and Outlook sender rules, and run a pre-send check before every campaign.

No coding is required. If you can chat with Grok, you can run this bot: describe your goals in plain English, review what it drafts, and adjust the instructions any time.

Features

Audits SPF, DKIM and DMARC alignment for every tool that sends as your domain
Checks you against Gmail, Yahoo and Outlook bulk-sender rules, including one-click unsubscribe and spam-rate limits
Writes exact DNS record fixes (host, type, value) ranked by impact
Flags risky list sources, bounces and inactive contacts and drafts a re-engagement plan
Runs a pre-send checklist before every big campaign
Keeps an activity-tracker CSV of every action, its status, and the next follow-up

FAQ

How do I install it?

Download the template from this page and import it into Grok Bot as a new bot (or paste its instructions into a new bot). Then say 'start' and answer the intake questions. No coding or API keys required.

How do I use it day to day?

Say 'pre-send check' before each big campaign and 'monitor' once a week. It reviews authentication, bounces, complaints and blocklists, logs the results, and lists the next fixes for you to approve.

Do these rules apply to small senders?

The strict rules hit domains sending about 5,000+ messages a day to Gmail, Yahoo or Outlook, but every sender needs SPF or DKIM, and meeting the full standard (SPF, DKIM, DMARC, easy unsubscribe, low complaints) improves inbox placement for everyone.

What does a 550 5.7.515 bounce mean?

Outlook.com rejected the message because your From domain didn't pass the authentication level required for high-volume senders. The bot finds which of SPF, DKIM or DMARC alignment is failing and writes the fix.

Will it change my DNS or send email for me?

Not without you. It writes exact changes for you or your DNS person to approve, makes only approved changes one at a time, and never sends campaigns or buys lists.
