    Per-client rules on your clients' own provider accounts.
  • Sales Development
    Verify every address. Parse every autoresponder for referrals.

    OOO replies are full of decision-maker names — capture them.

  • Financial Services
    DMARC compliance, audit log, signed webhooks.
  • Healthcare & Life Sciences
    Reliable patient comms with a full audit trail.

Industries — Nonprofit & Fundraising

Donor mail that lands, without a deliverability team.

Donor-appeal deliverability and DMARC compliance without hiring a deliverability specialist.

Deliverability without a team
Nonprofit & Fundraising

Four sendrules capabilities mapped to the pain that defines this segment. Every one of them is on the free plan.

  • Everything under one login
  • Auth-check with remediation
  • DMARC compliance %
  • Quality gate on the appeal list
The pain

What you deal with today.

Your appeal reaches the inbox or it does not. Every point of deliverability lost is a point of revenue lost — and nonprofits rarely have a dedicated deliverability specialist to babysit an ESP dashboard. DMARC is now mandatory at the big ISPs and your board is asking about it.

How sendrules answers

What changes when you route through us.

sendrules puts the deliverability suite under one login — DMARC monitoring with hosted rua, SPF/DKIM/DMARC graded A-F with remediation, blocklist and Postmaster tracking. Every send goes through the quality gate first so a dirty donor list doesn't tank your reputation. One platform, one bill.

The four capabilities

Feature per pain, not the other way round.

Everything under one login

DMARC, auth-check, blocklist, Postmaster, quality gate, activity — one dashboard, one bill. No need to buy four vendors and stitch them together.

Auth-check with remediation

SPF / DKIM / DMARC graded A through F with per-clause remediation copy. Fix the D grade before the appeal goes out.

Read more →

DMARC compliance %

Aggregate reports ingested per domain. Compliance % is the hero metric your board asked about. Sources classified so a forwarder isn't misread as spoofing.

Read more →

Quality gate on the appeal list

Every recipient scored in the SMTP DATA phase — syntax, suppression, disposable, role, typo. Bad addresses never reach your ESP.

Where it lands

Concrete scenarios you can wire in this week.

  • Annual appeal with the quality gate cleaning the donor list before the ESP sees it
  • Monthly newsletter with DMARC compliance % reported to the board in one screenshot
  • Legacy donor outreach on a strict rule with sender affinity so replies always come back to the same person
  • Volunteer coordination with the OOO parser capturing 'contact so-and-so instead' updates
  • Multi-programme setup — each programme is a tenant with its own DMARC posture and provider fleet
