Managing campaigns in Reach

Last updated: September 11, 2026

With Reach, you can send studies as campaigns directly to the segments you've created.

This article shows you how to set up your campaigns and, if you're on the Enterprise plan, use a custom email domain in your campaigns.

Campaigns can be sent to a maximum of 1000 participants at a time. Learn more about Reach usage limits

Current limitations

  • URL parameters aren't supported when sending out Reach campaigns.

  • In particular, it's not possible to disable unique sessions (?guerilla=true) in unmoderated studies sent via Reach. To allow participants to test the same unmoderated study multiple times, please use an alternative sharing option.

From Reach

  1. In Reach, open the segment you'd like to send a campaign to.

  2. Click Create campaign in the top right.

From the Recruit page

  1. Open the study you would like to test and publish it.

  2. The Recruit page gives you different options to invite participants to your study. To send your study directly to a Reach segment, click Email campaign.

Set up your campaign

The aspects of your campaigns that you can customize include:

Subject line

This is what participants will see first in their inbox. Make it short, snappy, and attention-grabbing for better responses.

It is automatically preset to "Help us test our new feature"

Sender name

Adjust how the sender name should appear to participants.

It is automatically preset to "Hello from [your name]'s [your team name]"

Recipients

Select the Reach segment you would like to send this study to.

Sender email

Reach emails are sent from a @mazetesting.com email address by default.

If you're on the Enterprise plan, you can send Reach emails from a custom email domain.

Reply to

Define who should receive the reply if recipients reply to the campaign email.

If a 'reply-to' address is not set, participants won't be able to reply to you.

E-mail body

Customize the email body to fit your brand, and share more information about the study.

You can use the following placeholders in the e-mail body, as well as the subject line and sender name:

  • {{ FirstName }} - The sender's first name

  • {{ LastName }} - The sender's last name

  • {{ TeamName }} - Name of the team

  • {{ Role }} - The sender's role

At the moment, we don't support other types of merge tags in Reach campaigns. If this is something you'd be interested in, please let our team know!

Attached study

Select the study you want to send out to be tested.

Signature

Hide or show a signature in your email.

In the signature, you can include an optional team or profile image, as well as two lines of additional information.

The team image is the one you've set in the team settings, whereas the profile image is the one you've set in your personal settings. 

Why is my logo cut off?

In some cases, you may notice that your team logo appears partially cut off. If you encounter this behavior, please reupload the image in the team settings, using the following dimensions:

  • Width: 71 px

  • Height: 48 px

  • Rounded corner: 12 px

  • Margin between the logo and the frame: 8 px

Use a custom email domain in your campaigns (Enterprise plan)

If your team is on the Enterprise plan, you have the option to send Reach campaigns from a custom email domain owned by you, instead of the @mazetesting.com default. 

To learn how to set up a custom email domain, please check out this article: Setting up a custom email domain in Reach

To send campaigns from a custom email domain:

  1. In the campaign modal, click the email domain under Send from.

  2. Select your custom domain from the dropdown.

  3. Click Add domain to be taken to your Campaign Settings to set up a custom domain.

Review & send

  1. Once you've set up your campaign, click Continue.

  2. Confirm all the details: sender name and email, reply-to-address, and subject line.

  3. Under 'Delivery', you can confirm the total number of people your campaign will be sent to. 

    This includes your selected segment, minus the participants who are a part of the segment, but are excluded from campaigns for one of the following reasons:

    • Unsubscribed: Participants who have opted out from receiving Reach emails

    • Duplicates: Participants who have already received the same study through a different campaign

    • Bounced: Participants with email delivery failures in previous campaigns.

  4. If you want to receive a test email before sending out the campaign, click Send preview.

  5. When you're ready, click Send.

Why aren't participants seeing my Reach emails?

Maze follows best practices to improve the delivery of emails sent from Reach campaigns. Notably, we use secure delivery methods to reduce the risk of our emails getting marked as spam by mistake.

However, Reach emails can still be filtered out, particularly if your participants' email service has additional security filters set up. If you're seeing very low response rates in your Reach campaigns, this might be the culprit.
