Mailrelay, the email marketing platform with the biggest free account

How to create an email campaign with Mailrelay

Your first campaign can be ready in four steps:

Import your contacts

Upload a CSV file or paste your list into the import field. Coming from Mailchimp? You can bring your contacts with you.

After that, your list stays clean on its own: bounces and unsubscribes are handled automatically. Organize your contacts in groups or with tags and add custom fields, such as company or city, to segment your sends.

1

Import your contacts easily
Design you email in minutes

2

Design your email

Use the drag-and-drop editor, start from a template or let the AI write a first draft. If you already have your own HTML design, you can upload it too.

Your designs adapt to mobile without you doing anything. You can personalize each email with the contact’s name or other fields, and even show or hide blocks based on their preferences with conditional content.

Send or schedule your campaign

Send it right away or choose the day and time. Not sure which subject line will work better? Run an A/B test with two subject lines or two senders and let your data decide.

You can also skip weekends or out-of-office hours, even if your contacts are in different time zones. And we send from our own IP ranges so your campaigns reach the inbox, however big the send.

Analyze results with statistics

4

Analyze your results

Opens, clicks, most clicked links, bounces, unsubscribes and spam complaints, campaign by campaign. That’s how you learn what to repeat and what to change. Don’t rely on generic advice about the best day or time to send: your own data will tell you what works for your list.

The click map shows you where your readers click inside the email. You can also export reports as CSV or PDF, or share them via a link with your team or your clients.

Automation, segmentation and forms on every plan

Sending the same email to everyone rarely works. These features are included even in the free plan:

Automation icon

Automation

Build workflows visually: welcome series, birthday emails, abandoned carts or follow-ups triggered when someone joins a group or gets a tag. You can also send SMS from your automations.

Segmentation icon

Segmentation

Organize your contacts with groups, tags and custom fields, and create segments with your own conditions. Each person gets the emails that are relevant to them.

Forms and landing pages icon

Forms and landing pages

Grow your list with signup forms and landing pages built from templates. You’ll see which ones convert. And every new contact joins your list because they chose to: permission is what gets you into the inbox.

Need more channels? From the same account you can also send SMS campaigns and WhatsApp campaigns.

Which plan do you need?

The free plan includes all these features. Paid plans add volume, priority sending and more support channels.

Frequently asked questions about email marketing software

What is email marketing software?

It’s a tool to create, send and measure emails to a list of contacts: newsletters, promotions or automated emails. Unlike your personal inbox, it manages signups and unsubscribes, takes care of deliverability and gives you statistics for every send. If you’re just getting started, our guide on what email marketing is explains the basics.

Why not send my campaigns from Gmail or Outlook?

Personal email is designed for one-to-one conversations. If you send a campaign to many people from your inbox, you risk showing every recipient’s address (which can breach the GDPR), hitting sending limits and landing in spam. Email marketing software handles bounces and unsubscribes automatically and helps your emails reach the inbox.

Is the free plan really free?

Yes. You can send up to 80,000 emails a month to 20,000 contacts with no time limit and without entering a credit card. Emails include the Mailrelay logo, which you can remove with an add-on, and the SMTP server is available as a 30-day trial.

Can I switch from another email marketing tool?

Yes. Export your contacts from your current tool as a CSV file and import them into Mailrelay with their custom fields. You can also bring campaigns you’ve already designed, so you don’t have to start from scratch.

How do I choose the right email marketing software?

Look at what you’ll really use: sending volume and number of contacts, automation, deliverability, reports and support in your language. That a competitor uses a tool isn’t reason enough. Test before you pay: with a free plan you can check all of this with your own list. If you want to compare options, read our guide to email marketing platforms.
