Industries — E-commerce & Retail

Order and marketing mail routed by your buyer's ISP.

Route Gmail buyers, Yahoo buyers, and Outlook buyers each through their best-fitting provider — from the same store.

Start freeAll industries
One rule per ISP
E-commerce & Retail

Four sendrules capabilities mapped to the pain that defines this segment. Every one of them is on the free plan.

  • Routing by inbox provider
  • Ramp-up with safety gates
  • Order vs marketing on separate rules
  • Autoresponder harvesting
The pain

What you deal with today.

Your buyers are on every major mail provider — Gmail dominates, but Yahoo and Outlook are still material. One provider that inboxes perfectly on Gmail may quietly get filtered on Yahoo. You never see it in your ESP dashboard because the mail was accepted; it just never reached the inbox.

How sendrules answers

What changes when you route through us.

sendrules checks each recipient's real mail server, not the domain string, and picks the provider best warmed for that inbox. Gmail buyers can leave through one provider, Yahoo through another, everyone else through a third — same rule, one send, no code change on your side.

The four capabilities

Feature per pain, not the other way round.

Routing by inbox provider

The strategy checks each recipient's real mail server and buckets them into Gmail, Yahoo, Outlook, Apple, or Other. Domain-string routing lies — many corporate domains are fronted on Google Workspace — and a real inbox check doesn't.

Ramp-up with safety gates

A new provider warms up on its own schedule. Bounce and complaint thresholds pause the ramp before you burn a fresh IP. No hand-tuning, no calendar reminder.

Read more →

Order vs marketing on separate rules

One rule for order confirmations that can never be rate-limited, another for marketing that can queue and drain overnight. Same providers, different limits — and marketing can never poison the transactional rail.

Autoresponder harvesting

Out-of-office replies from B2B buyers frequently name the person covering. The parser turns those into a fresh contact list you can add to the next campaign — delivered by webhook or CSV.

Where it lands

Concrete scenarios you can wire in this week.

  • Order confirmations and shipping updates on their own rule, so a Black Friday marketing burst can't rate-limit a checkout receipt
  • Post-purchase upsell campaigns routed by the buyer's inbox provider — Gmail through the warmest Gmail-friendly provider, Yahoo through another
  • Abandoned-cart mail with the quality gate rejecting mistyped addresses that would silently bounce
  • B2B wholesale outreach with the autoresponder parser lifting the covering colleague straight out of every out-of-office reply
  • Newsletter and campaign delivery with DMARC monitoring so a spoofing wave doesn't quietly kill your reputation
