1. Access the “Campaign Emails” section
From the main navigation menu on the left, go to Emails, then select Campaign Emails. You will see an overview of:
sent email campaigns
saved drafts
emails currently being sent
Click on “Create” to start a new campaign or select a predefined template from the Template Library.
2. Set a campaign title
At the top of the screen, enter a name in the “Title” field. This internal title is not visible to your recipients and is used solely for team organization and tracking.
Example: “Donation Appeal Lower Austria – April 2025”
Below you can deinde the key metadata for your email.
Subject: The subject line that will appear in the recipients’ inbox.
Sender Address: Choose the email address from which the campaign should be sent (must be previously configured at the Settings).
Preheader (optional): A short preview text shown in many email clients below the subject line.
Reply-to (optional): If replies should go to a different address than the sender, you can specify it here.
Note: The preheader should complement (not duplicate) the subject and offer additional value or clarity.
4. Edit the content of the email
Click on “Edit content” to open the campaign editor. You will be redirected to a separate editor where you can define layouts, text blocks, images, and personalization variables.
For a full explanation of the email editor, please refer to the separate help article: “Using the Editor”.
5. Send a test mail
Once you’ve created the content, you can send a test email to preview how it looks in an inbox.
Scroll down to the “Test mail” section.
Enter one or more email addresses (separated by commas).
Click on “Send test mail” to receive a sample.
Test emails allow you to verify formatting, content, links, and personalization variables before sending the final campaign.
If you changed the content of the email, it can take up to a minute to validate your changes. You will not be able to send a test email while the email is still being validated.
6. Select a target group
Navigate to the “Recipients” section by using the left-hand progress menu or clicking "Next".
Select one or several existing target groups from the dropdown list — the field is a multi-select, so you can add as many target groups as you like to one campaign email — or click “Create new target-group” to define a new one.
Sending to several target groups never sends the email twice. If a person is a member of several of the selected target groups, CamBuildr merges those groups into one recipient list and every person receives the email exactly once. This happens automatically: there is no setting to switch on, and you do not need to build a combined target group or exclude the groups from one another beforehand.
The number shown next to each group in the dropdown is that group’s own member count. When groups overlap, the sum of those numbers is higher than the number of emails actually sent. The de-duplicated recipient count is calculated when sending starts and is shown in the email’s statistics. People who have unsubscribed, who are blocked, or who have no email address are skipped as well, so the final number can be lower again.
The only way somebody receives the same content twice is if you duplicate the campaign email and send both copies.
7. Review and finalize your campaign
The final Summary step gives you a complete overview of the campaign configuration:
A visual preview of the email
The defined sender name and email address
The selected recipient group
At this point, you have the following options:
Send now: Send the email immediately
Plan: Schedule the email to be sent at a specific time in the future
Save & Close: Save your work as a draft to return to later
8. Optional: Add an A/B test variant
From the summary view, you can also create A/B test variants by clicking “+ Variant”.
This allows you to compare performance between different:
subject lines
content blocks
or design layouts
The A/B testing process works as follows:
When you send the email, a test cohort of 10% of your recipients is drawn at random and split evenly across your variants — with two variants, roughly 5% receives variant A and 5% variant B.
The test window is 1 hour by default. The value that applies to your account is shown on the email’s detail page, in the “Duration of sending” column of the variant table.
When the test window closes, CamBuildr picks the winner by your chosen metric (open rate or click rate) and queues it to the remaining recipients. Queueing runs on a 10-minute cycle, so the winning email starts going out within about ten minutes of the test window ending — not an hour later. If nothing has happened 20 minutes after the window closed, please contact support.
If your audience is smaller than 2,000 recipients, no staged test is run: the entire audience is split across the variants and all emails are sent immediately. There is no second send afterwards.
The test cohort size and the test duration are account-level defaults. They cannot be edited on an individual email — contact support if you need them changed.
