How it Works
Industries
  • All industries
    Every segment sendrules fits — and why.
  • B2B SaaS
    Transactional at scale. Failover across ESPs.
  • E-commerce & Retail
    One rule per ISP — Gmail buyers routed differently to Yahoo.
  • Marketing Agencies
    Per-client rules on your clients' own provider accounts.
  • Sales Development
    Verify every address. Parse every autoresponder for referrals.
  • Recruitment & Staffing
    OOO replies are full of decision-maker names — capture them.
  • Real Estate & Lead Gen
    Inquiry email hygiene + reply-source enrichment.
  • Financial Services
    DMARC compliance, audit log, signed webhooks.
  • Healthcare & Life Sciences
    Reliable patient comms with a full audit trail.
  • EdTech & Education
    Enrollment-week bursts absorbed by queue-don't-drop.
  • Nonprofit & Fundraising
    Donor-appeal deliverability without a deliverability team.
  • Publishers & Media
    Newsletter deliverability + list hygiene at every send.
  • Government & Public Sector
    IP allow-list at AUTH, DMARC-first, tenant isolation.

In the video

Six scenes. Every stage of a send.

The demo walks the exact path a message takes through sendrules — from your SMTP sendMail() call, through routing and verification, to the parsed contact that came back on an OOO reply.

    One endpoint

    Route, verify and warm up every send — over the providers you already trust.

  • 0:23

    Bring your own providers

    Attach SES, SendGrid, Postmark, Mailgun — 15 adapters in total. sendrules never resells sending.

  • 0:44

    Choose how to route

    Six strategies — round robin, weighted, priority, random, sticky sender, and MX-based ISP routing — with coverage warnings before you save.

  • 1:05

    Verify before the send

    Six checks inside the SMTP DATA phase — bad addresses never leave and never spend your ESP quota.

  • 1:25

    Autoresponder harvest

    Every OOO reply lands in a managed inbox. Rule-based parsers turn them into contact lists — CSV or webhook.
