How to Mail Merge with Gandi Mail (2026 Guide)

Your domain, your website, and your email address all live at Gandi, and now you’d like to send 70 customers an update that greets each of them by name. Gandi’s webmail can’t do it. Neither Roundcube nor SOGo has a mail merge feature, and an email sent from an app can carry 40 recipients at most.

The good news? You don’t need to change providers for that. You can plug your Gandi mailbox into Mailmeteor, a mail merge tool trusted by 7 million users, through SMTP, the standard protocol for sending email. Every customer then gets their own message from your Gandi address, with their details filled in.

Below, you’ll find the Gandi SMTP settings, Gandi’s sending limits and usage rules, and every setup step. The short version: mail.gandi.net handles both sending (port 465) and receiving (port 993), and you sign in with your mailbox password.

Here’s what we’ll cover:

Sounds good? Then let’s dive in.

Can You Mail Merge in Gandi Webmail?

No. Gandi offers two webmail interfaces, Roundcube and SOGo, and both can only send one identical message to everyone in To, Cc, or Bcc. Gandi also caps webmail emails at 15 recipients.

To send a personalized email to each contact, you need a tool that connects to your Gandi mailbox and sends one message per person, filling in each recipient’s details from a list. Mailmeteor does exactly that, using Gandi’s mail server.

Why Send Personalized Emails From Gandi Mail?

You already chose Gandi for your domain and your email. Keeping your outreach there means one less provider and one less sender for your customers to learn. Here’s what you get by connecting Gandi to Mailmeteor ⤵️

Send From the Domain You Built

Your emails come from your usual address, like marie@yourshop.fr, and go out through Gandi’s servers. Replies land in the Gandi mailbox you already read in Roundcube, SOGo, or your email app.

Fill the Gaps in Gandi’s Webmail

Gandi’s webmail covers day-to-day email well. But with Mailmeteor connected, your Gandi address can also:

• Send personalized emails to each customer.
• Import recipients from Google Sheets or a CSV file.
• Filter out invalid addresses before you hit send.
• Include an unsubscribe link, and automatically leave out anyone who opts out.
• See who opened your email, clicked a link, or replied.
• Send follow-ups automatically to the people who haven’t answered yet.

Stay Within Gandi’s Rules

Gandi states that its mailboxes are designed for standard email use, and that mass email campaigns may result in a suspended mailbox. That rules out newsletters to thousands of subscribers. But it leaves room for personalized emails to people who know you, at modest daily volumes.

What You Need to Mail Merge With Gandi Mail

To mail merge with Gandi Mail and Mailmeteor, you need:

• A Gandi Mail mailbox, Standard or Premium, on your own domain.
• The password of that mailbox, which is separate from your Gandi account password.
• A Mailmeteor Premium plan or above, which you need to add a custom sender like your Gandi address.

How to Mail Merge With Gandi Mail and Mailmeteor

The setup takes about 5 minutes. You register your Gandi address once, then pick it for each campaign.

Step 1: Register Your Gandi Mailbox as a Sender

1. Log in at dashboard.mailmeteor.com.
2. Under Products, expand More and click Senders.
3. Use the Add sender button.
4. Fill in your name as recipients should see it, along with your Gandi email address.
5. Store the sender by clicking Save.

Step 2: Point the Sending Server to Gandi

1. Add an email service with the + button in Email services.
2. Select Configure mail server.
3. Type mail.gandi.net in the Server name field under Sending server.
4. Use your full Gandi address, such as marie@yourshop.fr, as the Username.
5. Type your mailbox password in Password.

That’s the outgoing side configured. Mailmeteor picks the port and encryption itself, and both of the ports Gandi supports for apps (465 and 587) work.

Step 3: Point the Reception Server to Gandi

Without this step, your campaigns still go out, but Mailmeteor won’t know who answered, and an automatic follow-up could land in the inbox of someone who already replied.

1. In Reception server, set the Server name to mail.gandi.net as well. At Gandi, one server handles both directions.
2. Repeat your full Gandi address in Username.
3. Repeat your mailbox password in Password.
4. Click Save, followed by Done.

And voilà. Your Gandi mailbox is connected both ways, and Mailmeteor has filled in IMAP port 993 for you automatically.

Step 4: Prepare Your Personalized Emails

1. Kick off a campaign with New campaign.
2. Choose your Gandi address in the From menu (▼).
3. Click Select recipients and import your contacts from Google Sheets, a CSV file, an existing list, or by pasting addresses.
4. Compose the subject line and the body.
5. Add variables, for instance {{ firstname }}, wherever the email should change from one recipient to the next.
6. Flip through Preview to see several recipients’ versions and make sure each variable is filled in correctly.

Gandi caps a message at 40 recipients when it’s sent from an app like Mailmeteor, and at 15 from its webmail, which rules out Bcc for any real list. A mail merge avoids the problem, because every contact gets a message addressed to them alone.

Step 5: Spread Out the Sending With Autopilot

Gandi publishes generous technical limits, but it can suspend mailboxes used for mass campaigns. Autopilot keeps your pace closer to a person’s than a mailing tool’s.

1. Go to the Autopilot option of your campaign.
2. Restrict sending to working hours, such as Monday to Friday, 9 AM to 5 PM.
3. Pick the spacing between two emails. The minimum is one minute, and slower is safer.
4. Choose a daily cap. Around 50 is a reasonable start.
5. Hit Apply to save.

Before you confirm, Autopilot shows how long the campaign will take, so you can adjust the cap if a list would take longer than you’d like.

Step 6: Send Yourself a Test First

1. Send a test to your own address.
2. Check how it looks, and that every link and variable is right.
3. Click Send emails when you’re ready.

And that’s it. Your Gandi mailbox now sends each email in turn, and your Mailmeteor Dashboard keeps count of opens, clicks, and replies in real time.

Gandi Mail SMTP and IMAP Settings

Gandi uses the same server name for everything, which keeps the configuration simple:

Mailmeteor handles the security setting, so keep Security on Auto. For reference, Gandi uses SSL on port 465, and STARTTLS on port 587.

Gandi Mail Sending Limits and Usage Rules

Gandi publishes its limits, noting that the sending rates may vary:

Those numbers look high, but they’re not the real constraint. Gandi states that its mailboxes are designed for standard email use, and that mass email campaigns may lead to suspension. Its documentation also advises against using its SMTP server for larger mailings such as newsletters. So plan for personal outreach, like customer follow-ups, partner updates, or event invitations, at a few dozen emails a day.

Mailmeteor’s own plan limits cap your sending too.

How to Keep Your Gandi Emails Out of Spam

Gandi watches how its mailboxes are used, and inbox providers judge every email you send. Here’s how to stay on the right side of both ⤵️

Write Only to People Who Expect You

Gandi’s usage rules make this the most important habit. Email customers, partners, and contacts who gave you their address, and never a purchased or scraped list. Expected emails get opened and answered, instead of reported.

Remove Dead Addresses Before Each Send

Bounces signal a careless list to inbox providers, and to Gandi. Run your contacts through our free Email Checker before each campaign, or let Mailmeteor’s email verification filter out invalid addresses for you.

Make Each Email Read One-to-One

The closer your email looks to a message written for a single person, the more likely it is to reach the inbox:

• Mention something specific to each contact, not only their first name.
• Avoid spam words like “free”, “guaranteed”, or “act now”, especially in the subject line.
• Keep the layout simple, with a few short paragraphs and only the links that matter.
• Add an unsubscribe link to promotional emails, so uninterested contacts can opt out without reporting you.

Once your draft is ready, our free Spam Checker points out risky wording. Mail-Tester also shows whether your SPF, DKIM, and DMARC records pass and what in your content could trigger spam filters.

How to Fix Gandi SMTP Errors

Most Gandi connection problems come from the password, the type of address, or the port. Look for your situation below ⤵️
