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.

  • Teams and roles
    Fine-grained RBAC across 30 resource types + audit trail.
Deliverability

    Per-client rules on your clients' own provider accounts.
  • Sales Development
    Verify every address. Parse every autoresponder for referrals.

    OOO replies are full of decision-maker names — capture them.

    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.

Included on every tier

Same platform on every plan. Only the ceilings differ.

The table above only lists what actually changes between tiers — the quotas your workspace hits and the features that unlock as you move up. Everything below ships on every plan.

  • SMTP proxy on sendrules — one endpoint, port 587 (STARTTLS) + 465
  • Six routing strategies — round-robin, weighted, priority, random, sticky sender, MX-based ISP
  • Six-check Quality Gate (syntax, suppression, disposable, role, typo, cache) on every recipient
  • MX-based ISP classification + coverage warnings before you save a rule
Frequently asked

About the pricing

Do I keep my existing provider accounts?

Yes. sendrules is BYO-provider — you attach your SES, SendGrid, Postmark, Mailgun, SparkPost, Brevo, Resend, Mailjet, Zoho, Google Workspace, O365, or custom SMTP credentials. You keep their pricing, their IP warmth, and their sender reputation.

What counts as one email?

One recipient. A message to five addresses is five emails. Recipients caught by the Quality Gate before we hand them to a provider do not count against your monthly volume.

What happens when I hit a quota?

Start free. Upgrade when the volume calls for it.

Same routing, same quality gate, same dashboards on every plan — only the ceilings differ. Move up when you hit one; contact sales for anything above.

Start freeTalk to sales
Sender Affinity + Sender Map, and Brand-pin (Free / Preferred / Strict)
  • Blocklist monitoring (11 public DNSBLs) + seed-list inbox-placement testing
  • Single + bulk email validation and the DMARC record generator
  • Ramp-up engine with safety-hold gates and per-ISP delivery shaping
  • Suppression, allowlist and QC-failed lists (never counted against retention)
  • Full activity view, saved views, share links, keyboard shortcuts
  • IP allowlist at SMTP AUTH per credential, per-rule
  • The app shows an inline upgrade prompt where you tried the action — providers, rules, ramps, inboxes, parsers, DMARC domains, teams, roles, and workspaces all follow the same pattern. Nothing you already created is affected; only the next one is blocked until you upgrade or delete an existing item.

    What happens when I hit my monthly email cap?

    sendrules queues rather than drops. Your app keeps trying and messages are held until the next UTC-month rollover or until you upgrade to a plan with a higher cap. The dashboard warns at 80% used and again at 95%, so the ceiling never arrives as a surprise.

    Can I upgrade or downgrade at any time?

    Yes. Upgrades take effect immediately and are pro-rated on your next invoice. Downgrades take effect at the end of the current billing period so nothing you've already created is affected mid-cycle. Monthly and annual can be switched at the same time.

    Can I mix providers inside one routing rule?

    Yes — that is the point. Attach any number of providers to a rule and pick a strategy (round-robin, weighted, priority, random, sticky sender, or MX-based ISP routing). Failover on temporary errors is automatic.

    Do you offer dedicated IPs?

    On Enterprise. Every other plan runs on your attached providers' IPs, which is usually what our customers want — no second reputation to warm.
