Everything you need as a publisher

Integrate SendAs.me once. Your users authorize in one click. Your emails go out from their address.

SendAs.me admin portal — dashboard

Your users want emails to come from them — not from you

Invoices, notifications, reports, order confirmations: your customers expect these emails to arrive from their own professional address, not from a generic domain.

But asking for their Gmail or Office 365 password is out of the question. And implementing OAuth 2.0 yourself means weeks of development: registration on Google Cloud Console, token management, automatic refresh, revocation, secure storage…

SendAs.me does all of this for you. In minutes.

Asking for the password

Violates Google & Microsoft ToS. Liability on credentials. Immediate rejection by professional users.

Implementing OAuth yourself

Google Cloud Console, Azure AD, token management, auto-refresh, secure storage… 3 to 6 weeks of development minimum.

SendAs.me: three lines of config

Point your SMTP to smtp.sendas.me. Your users authorize in one click. Nothing else to do.

Everything you need

Integrate SendAs.me once. Your users authorize in one click. Your emails go out from their address.

Zero passwords to manage

Your users authorize via a standard OAuth link — exactly like 'Sign in with Google'. You never see their password. No liability for credentials, no additional compliance requirements.

No changes to your sending code

If your application already sends emails via SMTP, just point it to smtp.sendas.me. No new OAuth library to integrate, no redesign of your sending layer. You change three lines of configuration — that's it.

One connection link per user

Each of your users clicks a SendAs.me link, authorizes access to their Gmail or Office 365 account, and that's it. Your application can now send on their behalf — indefinitely, without any further action.

Portal, logs, and webhooks included

An admin portal to manage your applications and connected users. Detailed logs for every email sent. Webhooks to be notified in real time of each send or anomaly.

How it works

Three steps to send emails from your users' addresses.

1

Create an application in the portal

Sign up on SendAs.me and create an application in a few clicks. You get an SMTP identifier and an OAuth link to integrate into your user interface.

2

Add the connection link in your app

Integrate the 'Connect my email address' link into your interface. The user clicks, authorizes via Google or Microsoft, and their account is linked to your application. You are notified via webhook.

3

Your app sends via SMTP — emails go from their address

Configure your application to send via smtp.sendas.me with your credentials. Each email arrives at the recipient as if it were sent directly from your user's account.

Your app already sends emails? It's ready.

No need to rewrite your sending layer. Change the SMTP host, add your SendAs.me credentials — that's it.

# Before SendAs.me
host = "smtp.gmail.com"
user = "contact@votre-domaine.fr"
# With SendAs.me
host = "smtp.sendas.me"
user = "votre-app-id"
pass = "votre-send-key"
# Emails are sent from each user's own account

What publishers say

Technical teams who abandoned workarounds.

★★★★★

Our property management platform sends contracts and receipts from each landlord's email address. Before SendAs.me, we asked for an 'app password' — nobody understood what that was. Now it's a simple authorization click, and everything works.

We publish accounting software for small businesses. Our clients want their invoices to go out from their own Office 365 address. SendAs.me solved this in two hours of integration. Usage-based billing fits our SaaS model perfectly.

We build a client tracking tool for consulting firms. Each consultant sends their follow-up emails from their own Gmail account. SendAs.me saved us from implementing OAuth ourselves — a huge time saver, and our clients appreciate that their emails stay in their Google account.

Frequently asked questions

Do our users need to create a SendAs.me account?
No. Your users only see the standard OAuth authorization flow from Google or Microsoft. SendAs.me is invisible to them — it's infrastructure you use as a publisher. Only you have an account on the SendAs.me portal.
How does SendAs.me integrate with our existing application?
In two steps: (1) add a 'Connect my email' link in your interface pointing to your SendAs.me authorization URL; (2) configure your SMTP sending layer to point to smtp.sendas.me with your application credentials. No other code changes needed.
What happens if a user revokes access?
You immediately receive a user.disconnected webhook. You can then display a message in your interface inviting the user to reconnect their account. Emails to that user will fail cleanly with an explicit error code until reconnection.
Is billing per application or per mailbox?
Billing is per connected mailbox, across all applications. Each OAuth account (Gmail or Office 365) authorized counts as one license, regardless of which user connected it. If a user connects Gmail AND Office 365, that counts as 2 licenses.
