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.

Real stories, when the customer signs off.

Most B2B sites pad the logo wall with brands that trialled the free tier once and never came back. We don't. When a customer agrees to be named — and to publish the numbers that back the story — you'll see it here. Until then, this page tells you honestly what teams do with sendrules.

How we do customer proof

Three rules.

  • Only real customers, only with permission. No logo goes on this page or the homepage unless the account is active, the company has agreed in writing, and the person quoted has approved the exact words.
  • Numbers must be verifiable.If a case study says “bounce rate dropped 37%”, that number came from the customer’s own Activity data — not from our marketing team.
  • No named-drop logo padding. A logo without a story attached is a decoration, and buyers know it. Every logo we render will link to a story the person named in it stands behind.
What teams do with sendrules

Three patterns that repeat.

While we build the case-study library, here’s an honest look at what teams actually use sendrules for — the moves the platform is built around.

Route around a bad afternoon

Provider A had an outage in April. Teams sending through sendrules kept sending — every rule fails over to the next attached provider before the message queues.

Keep sender reputation clean

One recycled list can burn a warmed-IP reputation. Teams point their sequencer at sendrules and the quality gate rejects typos, disposables, and role addresses before the ESP sees them.

Turn every OOO reply into a lead

Recruiters, sales teams and account managers use the autoresponder parser to pull the covering colleague's email straight into a follow-up list — every reply their ESP would have thrown away.

If you send through sendrules and you’d like to be featured — either as a named case study or, if you’d prefer, as an anonymous one with a job-title-and-industry attribution — write to us and we’ll take it from there. You approve every word before it goes live.
