The comparison · Mailstinger vs. PowerDMARC

PowerDMARC prices per domain. We don't.

Scale your fleet from 5 to 50 clients on PowerDMARC and your bill 10x's. Same thing on Mailstinger goes $49 → $149. That's the entire pitch.

Credit where it's due

Here's what PowerDMARC genuinely does well.

No false dichotomy. If these are deal-breakers for your context, they might be the right choice. We'd rather you buy the right tool than hate us in six months.

  • Explicit per-domain pricing you can calculate in a spreadsheet — more transparent than some of the enterprise category.
  • Active channel partner program; if you're a reseller who wants branded co-sell motions with a partner org behind you, they have that.
  • Good coverage of BIMI + MTA-STS + TLS-RPT in the base product, not as add-ons.
§02 · Where we diverge

Capability by capability. Everything listed here is verifiable.

No hand-waving. If we claim a feature, it's shipped and you can test it free on the analyzer. If we claim a competitor doesn't have something, it's because their docs / pricing page / product tour say they don't.

Pricing shape
Mailstinger
Flat tiers — know your renewal.
PowerDMARC
Per-domain linear — your price grows with your success.
ESP-aware verdicts per sender
Mailstinger
Every sender row classifies as aligned / misaligned-ESP (benign) / misaligned-suspicious (spoof). Distinguishes Mailchimp forgot-to-sign from a VPS in Bucharest.
PowerDMARC
Pass/fail + percentage. Operator does the classification.
Paste-ready DNS fixes inline
Mailstinger
Yes — every finding carries the literal TXT to publish, with copy-to-clipboard.
PowerDMARC
Recommendations surface; fix workflow lives in a separate 'DNS Timeline' tool.
Hosted SPF + auto-flatten
Mailstinger
Yes — 22 ESP catalog, 1-click add from /reports, auto-flatten at 10-lookup cap.
PowerDMARC
Hosted SPF available; catalog-driven authorise-from-report isn't their workflow.
Tone-aware transactional alerts
Mailstinger
Alerts strip bulk markers so they don't train filters as newsletters.
PowerDMARC
Standard pipeline.
The honest verdict

PowerDMARC is a reasonable product at small scale. It becomes expensive at the moment it's supposed to be paying off — when your fleet grows. Flat pricing changes the unit economics enough that the migration is worth doing once, not every renewal.
