How to Send Email Campaigns from OVH (2026 Guide)

Need to send the same email to 150 clients, prospects, or partners from your OVH address, with each message personalized with their name and a custom line? OVH Webmail doesn’t support mail merge, and sending 150 emails in BCC can quickly trigger sending limits or get your mailbox blocked.

The simplest solution is to connect your OVH mailbox to Mailmeteor, a mail merge tool trusted by 7 million users, through SMTP (the protocol that sends your emails). You can then send email campaigns directly from your own OVH address, with each recipient receiving a separate, personalized email instead of a mass BCC message.

This guide walks you through the SMTP settings for each OVH offer, explains the relevant sending limits, and shows you how to connect your OVH mailbox to Mailmeteor and send your first campaign.

Here’s what we’ll cover:

• Why send email campaigns from OVH?
• What you need to send email campaigns from OVH
• How to send email campaigns from OVH with Mailmeteor
• OVH SMTP and IMAP settings
• OVH sending limits
• How to keep your OVH emails out of spam
• How to fix OVH SMTP connection errors

Sounds good? Then let’s dive in.

Why Send Email Campaigns From OVH?

Your OVH mailbox is already a good sending address. What it lacks is the campaign layer. Here’s what connecting it to Mailmeteor gives you ⤵️

Keep Your Professional Address

Your recipients see the address they already know, such as [email protected], and replies land in your usual OVH inbox. You don’t need a separate sending domain, a new provider, or a DNS overhaul.

Add What OVH Webmail Lacks

OVH webmail is built for one-to-one email. Connect it to a mail merge tool like Mailmeteor and you can:

• Personalize each email with variables like first name or company.
• Import your contacts from Google Sheets or a CSV file.
• Track opens, clicks, and replies to see who’s interested.
• Schedule your campaign and send follow-ups automatically.

Know the Trade-Off

OVH recommends a dedicated mailing list service for mass mailings, and its anti-spam system can block addresses that send too much, too fast. Your mailbox works well for personal outreach, such as prospecting, client updates, or payment reminders. For newsletters or more than a few hundred emails a day, a newsletter platform is safer for your sender reputation.

What You Need to Send Email Campaigns From OVH

Before you start, check that you have:

• An email address hosted by OVHcloud (MX Plan, Email Pro, or Hosted Exchange).
• The password for that mailbox. This is not the password of your OVHcloud customer account.
• A Mailmeteor account. Custom senders are available starting from the Premium plan.

Not sure which OVH offer you have? Log in to the OVHcloud Control Panel and open the Web Cloud tab. Your email service appears under MX Plan, Email Pro, Exchange, or Zimbra Mail. You’ll need this information in the next step, because each offer uses different servers.

How to Send Email Campaigns From OVH With Mailmeteor

The setup takes about 5 minutes. You’ll connect your OVH mailbox once, then pick it as your sender for every campaign.

Step 1: Create a Sender

1. Sign in to the Mailmeteor Dashboard.
2. Under Products, click More > Senders.
3. Click Add sender.
4. Enter your name and your OVH email address.
5. Click Save.

Step 2: Connect Your OVH Sending Server (SMTP)

1. Next to Email services, click the + button.
2. Select Configure mail server.
3. Under Sending server, enter ssl0.ovh.net in the Server name field.
4. Enter your full OVH email address in the Username field.
5. Enter your mailbox password in the Password field.

All done. Mailmeteor fills in the port and detects the security type for you.

Step 3: Connect Your OVH Reception Server (IMAP)

This step is optional, but skip it and Mailmeteor can’t detect replies. That means follow-ups could still go out to people who already answered you.

1. Under Reception server, enter ssl0.ovh.net in the Server name field.
2. Enter your full OVH email address in the Username field.
3. Enter your mailbox password in the Password field.
4. Click Save, then Done.

And voilà. Mailmeteor fills in port 993 automatically, which is the IMAP port for every OVH offer. Your OVH mailbox is now connected to Mailmeteor.

Step 4: Create Your Campaign

1. In the Mailmeteor Dashboard, click New campaign.
2. In the From field, click the caret symbol (▼) and select your OVH sender.
3. Click Select recipients and import your contacts from a Google Sheet, a CSV file, a contact list, or by copy-pasting addresses.
4. Write your subject line and email.
5. Add variables to personalize each email, such as {{ firstname }}.
6. Click Preview to check how the email looks for each recipient.

Prefer to work from a spreadsheet or a doc? Your OVH sender is also available in Mailmeteor for Google Sheets and Mailmeteor for Google Docs. Select it in the From field the same way.

Step 5: Pace Your Campaign With Autopilot

This is the step that keeps you under OVH’s hourly limit. Autopilot spaces out your emails instead of sending them all at once. Here’s how to set it up.

1. In your campaign, click Autopilot.
2. Choose the days and hours you want to send (for example, Monday to Friday, 9 AM to 5 PM).
3. Set the delay between emails to 1 minute.
4. Set a daily limit that fits your plan and your list size.
5. Click Apply.

At one email per minute, your campaign sends at most 60 emails per hour, well below OVH’s limit of about 200 on MX Plan. A list of 150 contacts goes out in about two and a half hours. Mailmeteor also shows an estimate of how long your whole campaign will take.

Step 6: Send a Test, Then Launch

1. Send a test email to yourself.
2. Check the formatting, links, and personalization in your inbox.
3. Click Send emails to launch your campaign.

And that’s it. Your campaign now goes out from your OVH address, at a pace OVH is comfortable with. You can follow opens, clicks, and replies directly from your Mailmeteor Dashboard.

OVH SMTP and IMAP Settings

Mailmeteor needs two servers to work with your OVH mailbox:

• The sending server (SMTP) sends your emails.
• The reception server (IMAP) detects replies and bounces.

Here are the settings for each OVH offer:

For every offer, the username is your full email address, and the password is your mailbox password. Mailmeteor detects the security type for you. For reference, OVH lists port 465 as SSL/TLS and port 587 as STARTTLS.

For every offer, the username is your full email address, and the password is your mailbox password.

A few details matter here:

• For MX Plan, smtp.mail.ovh.net and imap.mail.ovh.net point to the same server as ssl0.ovh.net. Either works.
• For MX Plan in the Americas and Asia-Pacific, use smtp.mail.ovh.ca and imap.mail.ovh.ca. The ports stay the same.
• For Email Pro and Hosted Exchange, replace the ? with your server number. You’ll find the full server name in the Connection box of the General information tab of your service in the OVHcloud Control Panel (for example, pro3.mail.ovh.net).
• If the connection fails, check the port. In Mailmeteor’s Advanced options, use 465 for MX Plan and 587 for Email Pro and Hosted Exchange. Keep Security on Auto.

OVH Sending Limits: What You Need to Know

OVH caps how many emails each mailbox can send. Go over the limit and your emails bounce back with an error. Keep going, and OVH may block your address for spam. In practice, 200 emails per hour is plenty for personal outreach, as long as you spread your campaign out

Mailmeteor’s plan limits also apply on top of OVH’s. Connecting an SMTP server doesn’t unlock unlimited sending.

How to Keep Your OVH Emails Out of Spam

Connecting your OVH mailbox doesn’t guarantee that your emails reach the inbox. When OVH emails go to spam, the cause is usually missing authentication records for your domain (SPF, DKIM, and DMARC), a list with invalid addresses, or content that triggers spam filters. Here’s how to improve deliverability from OVH ⤵️

Check Your SPF and DKIM Records

SPF, DKIM, and DMARC are DNS records that help email providers check that your emails really come from your domain. Without them, providers like Gmail, Outlook, and Yahoo are more likely to send your messages to spam or reject them.

• SPF: Make sure your domain’s SPF record includes OVH’s servers (include:mx.ovh.com).
• DKIM: Enable DKIM signing for your domain in the OVHcloud Control Panel.
• DMARC: Add a DMARC record to tell receiving servers what to do with unauthenticated emails.

Clean Your List Before Sending

Bounces hurt your sender reputation, and OVH’s anti-spam system watches them. Run your list through our free Email Checker or turn on automatic email verification in Mailmeteor to skip invalid addresses.

Avoid OVH’s Spam Triggers

OVH scans your emails as they’re sent. It blocks an address when it finds suspicious elements in a message, or when the sending frequency and number of recipients look like spam. OVH’s anti-spam guidance for its server customers recommends:

• Avoid spammy words like “buy” or “last chance”, capital letters, exclamation marks, and percentage discounts.
• Write a specific subject line, not an impersonal one.
• Keep a healthy balance of text, images, and links, and don’t overload your email with links.
• Add an unsubscribe link.

To test your draft before sending, run it through our free Spam Checker or an external tool like Mail-Tester.

Start Small

If you’ve never sent more than a few emails a day from your OVH address, don’t jump to 500. Start with a small batch, check your results, and increase gradually. For more tips, see our guide on how to improve your email deliverability.

How to Fix OVH SMTP Connection Errors

If Mailmeteor can’t connect to your OVH mailbox, or your emails aren’t sending, the cause is usually the wrong password, the wrong port, or OVH’s limit of about 200 emails per hour on MX Plan. Here’s how to fix these issues ⤵️
