How to Change Your Email Sender Address
The "from" address on your booking emails isn't a free-text field — not in meetergo, and not in any other booking tool. It's a technical limitation of how email works: modern providers (Gmail, Outlook, etc.) reject mail sent from addresses the sender isn't verified to use. Allowing it would mean your invites land in spam, if they arrive at all.
What you can choose is which system sends the email, and the sender address follows from that. Below are your options, from the simplest setup to the most customizable.
This article is about the sender address (the actual email account messages are sent from). To change the display name that recipients see (e.g. "Sales Team" instead of "Acme GmbH"), or to switch between a branded and no-reply reply-to, see Customize Your Email Sender Name.
Quick overview — which option fits you?
| You want… | Use |
|---|---|
| The simplest setup, with deliverability handled for you | meetergo email confirmations |
| Invites that arrive from your own personal email and calendar | Calendar invites |
| Every meetergo email to be sent from your company's own mailbox or server | Connect your own email (M365 or SMTP) |
You don't have to commit forever — you can change the option per Meeting Type and switch later.
Option 1: meetergo email confirmations (default, easiest)
When a Meeting Type is set to send "Email confirmations", meetergo sends the email from its own optimized system address (e.g. noreply@meetergo.com). The reply-to is set to the host's email, so attendees can still reply to you directly.
Best for: users who don't need invites to come from a specific personal or company address, and just want messages to land reliably in the inbox.
This option requires no setup — it's the default.
You can customize the display name ("From Name") and toggle a no-reply reply-to under Admin → Emails → Branding. See Customize Your Email Sender Name for the details.
Option 2: Calendar invites (recommended for individuals)
If you want invites to actually arrive from your own email address, switch the Meeting Type to send "Calendar invites". meetergo will tell your connected calendar (Google, Microsoft, or Exchange) to send the event invitation, so the invite comes directly from the email address tied to that calendar.
Attendees see your name and email address as the sender, and replies go straight to your inbox.
Best for: individual users — sales reps, consultants, anyone who wants invites to feel like they sent it themselves.
To switch to Calendar Invites:
- Go to your Meeting Types.
- Find the Meeting Type you want to change and click "Edit".
- Scroll down to the "Communications" section.
- Under "Email Confirmations", select "Switch to Calendar Invitations".
- Click Save.
This requires a calendar connection in your Integrations settings. If you haven't connected one yet, meetergo will guide you through it.
Option 3: Connect your own email (most control, fully branded)
If you want all meetergo emails — confirmations, reminders, follow-ups — to be sent from your own company mailbox or mail server, you can connect your own email provider. meetergo will route messages through your infrastructure, so the sender address is fully under your control and consistent across every email your attendees receive.
Today we support the two integrations below. They cover most setups — Microsoft 365 directly, and anything else via SMTP — but they're not a hard limit on what's possible. If you use a provider that needs a direct integration (Google Workspace OAuth, a specific transactional API, etc.), let us know — we add native connectors based on what customers actually run.
Microsoft 365 (OAuth) — easiest
If your organization runs on Microsoft 365, you can connect your M365 mailbox with a one-click OAuth authorization. No passwords are stored, no server settings to configure. After connecting, all meetergo emails go out from your M365 address.
This is the right choice if you're a Microsoft 365 user and want branded emails without touching technical settings.
Custom SMTP — works with any mail server
If you don't use Microsoft 365 — or you have a dedicated transactional mail provider (Postmark, Mailgun, AWS SES, your own mail server, etc.) — you can configure meetergo to send through any SMTP server. You'll need the host, port, and credentials from your mail provider.
This option gives you the most control, but it does require some technical setup.
FAQ
Why can't I just type in the email address I want to use?
Because letting anyone send mail from any address is exactly what spammers do. Modern email providers (Gmail, Outlook, etc.) reject or spam-folder messages that aren't sent from a verified source. The options above all use a verified source — either ours, your calendar provider's, or yours — so your invites actually reach attendees.
If I use Calendar Invites, can attendees reply to the invitation?
Yes. Replies go directly into the inbox of the calendar account you connected (your Gmail, Outlook, etc.).
What's the best option for me?
- Most individual users → Calendar Invites. Personal, professional, replies land in your inbox.
- Don't have Google, Microsoft, or Exchange → meetergo email confirmations. Simple and reliable.
- Microsoft 365 user who wants branded emails across the company → Microsoft 365 Email integration.
- You have your own mail server or a transactional provider → Custom SMTP.
