Sending infrastructure

Nothing sends until a person says so.

SendCopilot drafts replies to the email a local service business already receives — pricing questions, scheduling, “do you cover my street” — and sends them only after the business owner has read and approved that exact message. Nothing leaves on its own.

This domain carries client mail only. Every business sends from its own authenticated subdomain — business.sendcopilot.com — so one sender’s reputation is never pooled with another’s.

“Hi — do you service the east side of the valley, and what’s the call-out fee for a leaking water heater?”

Drafted reply

Hi Dana — yes, we cover the whole east valley, no travel surcharge.

Our call-out is $95, credited against the repair if you go ahead on the day. For a leaking water heater we’d usually want to see it same-week. Would Thursday morning suit?

Waiting on the owner

Illustration only. Not a real customer, business, or message.

At a glance

Reply-only

Mail goes to people who wrote to the business first. No campaigns, no lists, no cold outreach — ever.

One subdomain per business

SPF, DKIM and DMARC are published for each subdomain before it is allowed to send a single message.

A human clicks send

Approval is a person reading one specific draft. There is no bulk approve, and no scheduled autopilot.

How mail leaves here

Four steps, and a person stands in the middle of them.

The order matters more than the technology. Everything upstream of step three is a suggestion; only step three creates mail.

  1. A customer emails the business

    At the address that business gave them. Nothing enters the system that a customer did not send to a business directly.

  2. SendCopilot drafts a reply

    It sorts the message into a small fixed set of everyday categories and writes an answer from that business’s own published details — services, hours, service area, prices. Urgent and unclassifiable mail is never drafted; it goes straight to the owner untouched.

  3. The owner reads it and decides

    Send it, edit it first, or throw it away. A draft nobody approves is a draft that never becomes an email. This boundary is structural, not a setting — there is no configuration that turns it off.

  4. It sends from the business’s own subdomain

    Signed, and threaded to the original message, so the customer’s reply lands back in the inbox the business is already watching — not in a no-reply void.

Acceptable use

What this domain sends, and what it will never send.

The second list is not a policy waiting to be enforced. Those things are outside what the software is built to do — there is no code path that performs them.

It sends

  • Replies to inbound customer email — answers to a question that person asked the business.
  • One message to one recipient, written for that conversation and no other.
  • Only after a named person approved it, with the approval recorded against that draft.
  • Identified as the business it is from — the business’s own name, its own subdomain, its own reply address.

It never sends

  • Bulk or marketing campaigns. There is no campaign builder, no audience selector, no send-to-many path in the product.
  • Cold outreach or prospecting of any kind, to anyone.
  • Newsletters, promotions or announcements — including to a business’s own past customers.
  • Mail to purchased, scraped or uploaded lists. There is no import. Recipient addresses only ever come from inbound mail.
  • Anything the software decided to send by itself.

Sending practices

The guardrails, in the order they would catch something.

Written out because a sending domain should be legible to the mailbox providers, blocklist operators and email vendors who have to make a judgement about it.

Authentication
SPF, DKIM and DMARC are published for a business’s subdomain at provisioning, before the first message. A subdomain that is not fully verified cannot send.
Isolation
One business, one subdomain. Client mail is also kept on separate sending infrastructure from the operator’s own mail, so neither can affect the other’s standing.
Consent basis
Inbound-initiated. The recipient of any message wrote to that business first, at an address the business published. There is no other way for an address to enter the system.
Automatic suspension
Sending pauses for a business that crosses 5% hard bounces or 0.3% complaints over a rolling 30 days — or 3 complaints at any volume at all, which deliberately applies from the very first send. A paused business keeps its drafts; it just cannot send them.
Operator stop
A single manual control halts sending for every business at once, taking effect immediately and without a deployment. It exists for the failure the thresholds did not anticipate.
Duplicate protection
Each outbound message carries a unique identifier enforced at the database level, so a retry or a double-click cannot put two copies of a reply in someone’s inbox.
Threading
Replies carry correct In-Reply-To, References and Reply-To headers, so the conversation stays in one thread and the customer’s answer reaches a monitored inbox.
Delivery outcomes
Bounces and complaints are recorded per message against a rolling window, not as a counter that only ever climbs — a business that had a bad week can recover, and a business with a live problem is visible while it is live.
Message content
Used to classify the message and draft a reply for that business’s owner. It is not sold, not shared between businesses, and not used to train models.

If you received one

You got an email from a subdomain of sendcopilot.com.

That means a local business you contacted uses SendCopilot to answer its email. The reply came from that business, not from us — a person there read it and approved it before it was sent.

Just reply as normal. Your answer goes straight back to the business’s own inbox. If you would rather they didn’t email you again, say so in that reply and it will be honoured. If the message looks like something a business would not send, tell us at abuse@sendcopilot.com — that is a real address, read by a person.
