Email deliverability, fixed properly.
Your domain says things about your mail whether you configured it or not. We check what it's saying, and hand you the exact records to fix it.
Fixed scope: the three DNS records that authenticate your mail. Content filtering, IP reputation and platform throttling are outside what records can fix.
Three fields, one reply.
Public DNS only. No account, no DNS access, no sales call. Results land in your inbox the same business day.
Prefer email? Write to hello@authpulse.io with your domain; that works too.
Three steps, one of which is doing nothing.
Send us your domain.
The form above, or a plain email. Just the domain, like yourcompany.com. Nothing to install, no account to create.
We scan and reply.
SPF, DKIM and DMARC, checked by hand-reviewed tooling, with plain-language results usually the same business day.
Fix it or don't.
If something's broken you can buy the Protocol below, or take the results and do nothing. Both are fine answers.
What broken records cost you.
Anyone can send email that looks like it came from you.
Your real mail lands in spam
Receivers drop or junk what fails SPF, DKIM and DMARC. You find out from the deals that never answered.
Anyone can spoof you
Without DMARC, mail that impersonates your domain reaches your customers looking exactly like yours.
You can't see either happening
No DMARC record means no reports. The two problems above stay invisible until someone shows you.
Google and Yahoo now require DMARC for bulk senders, so this stopped being optional in 2024. Scan your domain to see where it stands.
The Deliverability Remediation Protocol
A document for your domain, with every DNS record you need: exact values ready to paste into your DNS panel, ordered so nothing breaks your existing mail while you apply it.
Secure checkout via Stripe; we never see your card details. The Protocol is a document you apply yourself; we never touch your DNS.
- We don't fix content-based spam filtering or burned IP reputation. If that's your problem, we'll say so rather than sell you the wrong thing.
- Our scan checks public DNS records. We never need access to your mail, your accounts, or your customer data.
v=DMARC1; p=quarantine; rua=mailto:dmarc@yourdomain.com
Illustrative example, not a recommendation: your protocol's values depend on what your scan shows. The real document walks several records like this, in order.
- The exact DNS records for your domain: host, type, TTL and value, ready to paste.
- The order to apply them in, so existing mail keeps flowing while you work.
- What each record does, and why your value is what it is, in plain language.
- How to verify each record landed and took effect, with the commands to run.
- What we deliberately left alone, and why.
- Support while you apply it: we re-scan and confirm if you ask.
AuthPulse is run by one person from the Netherlands, founded 2026. Scans are run by our own tooling and checked before anything is sent. Questions reach the same mailbox the scans come from: hello@authpulse.io.
- Full legal name and postal address on request, and on every invoice.
- Payments run through Stripe; we never see your card details.
- 14-day full refund for any reason, and you keep the document.
- Dutch law governs the terms; terms and privacy are linked in the footer.
