Product
  • Overview
    How sendrules fits between your app and every provider.
  • SMTP Proxy
    One endpoint. Every provider you already trust.
  • Grid & Rules
    Six routing strategies. Coverage warnings. Failover.
  • Quality Gate
    Verify recipients before the send, not after the bounce.
  • ISP Routing
    Route by the recipient's live MX record — not domain strings.
  • Ramp-up
    Auto-advancing cap with bounce/complaint safety gates.
  • Limits & Queue
    Four-tier caps. Queue, don't drop. Midnight-UTC release.
  • Webhooks
    Signed and verifiable. Retried on schedule. Replayable.
  • Activity
    Seven filtered inboxes. Sparklines. Share links.
  • Inbound
    Receive + classify replies, bounces, and OOOs.
  • Autoresponder Parser
    Harvest contacts from OOO replies into lists — webhook or CSV.
  • REST API
    Every UI action has an endpoint. Scoped, rotatable keys.
  • Teams and roles
    Fine-grained RBAC across 30 resource types + audit trail.
Deliverability
  • Overview
    The suite most vendors sell separately.
  • DMARC Monitoring
    DMARC aggregate reports ingested with per-source breakdowns.
  • Auth Check
    SPF / DKIM / DMARC, graded A through F.
  • Postmaster Tools
    Google Postmaster data in per-domain views.
  • Blocklists
    Continuous blocklist + seed-list inbox placement.
  • Free Tools
    Email validation, spam check, DMARC generator — free on every plan.
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.
