In their own words
dmarcian

These reports can reveal SPF and DKIM authentication gaps, unauthorized domain use and potential security threats. Alert Central can send notifications by email, Slack, Teams or webhooks. Plans differ in domain, user, message-volume and data-history allowances: Basic costs $19.99 a year, Plus costs $199 a year, and Enterprise costs $499 a year, all billed yearly. Personal is for non-business use and allows up to two active domains and 1,250 DMARC-capable messages per month; no price is listed for it. Enterprise adds automatic discovery of domains, subdomains and related email infrastructure, plus REST API support for webhook notifications and batch processing. Enterprise SSO includes SAML, user provisioning and deprovisioning, role-based access controls and audit logging. The service is available on the web and as a progressive web app through Chrome, Edge, Brave or Safari. dmarcian offers a free plan and a 30-day trial. Its regional instances include the Americas, APAC, Australia, Canada, EU and Japan, with customer data hosted in those regions.
Postmark
Postmark delivers and tracks application email as an alternative to SMTP or Sendmail. It separates transactional and broadcast messages into different Message Streams and IP infrastructure. Developers can send through REST API, SMTP, or multi-region SMTP routing, with official libraries for Node.js, Python, Rails, Ruby, PHP, and.NET. Inbound messages can be converted to JSON and sent to a webhook URL. Tracking includes delivery, bounces, spam, opens, and links, with event webhooks. Editable responsive templates cover transactional messages such as password resets, receipts, and invitations. The free Developer plan costs nothing, provides 100 emails per month, permits no overages, and does not expire. Basic starts at $15 a month for 10,000 emails per month; extra emails cost $1.80 per 1,000 and are calculated at the end of the billing cycle. Unused emails do not roll over. Postmark lists API and web access. Its iOS app was sunset in June 2025 and is no longer supported.
