Deliverability
What free email deliverability tools does Warmerly have?
Warmerly publishes seven free tools on warmerly.com/tools. You do not need an account, and none of them sends an email. They tell you what is true about a domain or a draft today. For the same checks run automatically on your connected mailboxes, with alerts when something breaks, use the Health tab of a mailbox (domain health card).
The tools
| Tool | Use it to | Link |
|---|---|---|
| Deliverability checker | Check any domain's SPF, DKIM, DMARC and MX records in one go, with plain-English fixes. No test email is sent | warmerly.com/deliverability-checker |
| SPF record checker | Validate an SPF record: a single record, the 10 DNS lookup limit, and a safe ending (not +all or ?all) | warmerly.com/spf-checker |
| DMARC checker | Look up a DMARC policy (none, quarantine or reject), its reporting address, pct and alignment | warmerly.com/dmarc-checker |
| Email blacklist checker | Check a domain, or a mail server IP, against Spamhaus, SURBL, URIBL, SpamCop and other lists, with removal links | warmerly.com/blacklist-checker |
| Spam word checker | Scan a subject line and body for spam-trigger phrases and get a risk score with rewrite tips | warmerly.com/spam-word-checker |
| Email HTML checker | Check text-to-HTML ratio, image and link counts and tracking pixels in a draft. Runs in your browser | warmerly.com/email-html-checker |
| Warmup calculator | Get a day-by-day sending ramp based on mailbox age, provider and target volume | warmerly.com/warmup-calculator |
Which one for which problem
- "Is my domain set up properly?" Start with the deliverability checker, then use the SPF and DMARC checkers for a closer look. Fix guides: DNS checklist, DKIM, SPF & DMARC.
- "My email is going to spam." Run the blacklist checker, then the spam word checker on your copy, then the HTML checker on your template.
- "How fast should I ramp a new mailbox?" Use the warmup calculator to see a schedule, then see How warmup works for how Warmerly's own ramp behaves.
What the free tools cannot do
- The blacklist checker uses the same lists and rules as Warmerly's own checks. A list that could not answer is shown as unknown or not checked, never as clean.
- They are point-in-time. A checker tells you the answer right now. Warmerly's Health tab re-checks DNS regularly and blocklists about every six hours, and alerts you.
- The spam word checker and HTML checker are guides, not verdicts. Inbox providers do not publish their filters. A low score does not guarantee delivery, and a high one is a reason to reword, not proof of spam.
- They do not read your mailbox or send test mail. To see where a real message lands, run a placement test from a connected mailbox.
- The DKIM check may not find a custom selector. DKIM is found by trying common selector names. See Troubleshooting.
Warmerly also checks copy for you
When you start a campaign, Warmerly runs a readiness check that can warn about sender DNS that is not passing, too many mailboxes on one domain, tracking without a verified tracking domain, and email copy with a high spam score, many links or many images. These are warnings you can acknowledge, not blocks. See Launch your first campaign.
