When you create or open an email in the content builder, the email settings appear in the top part of the screen. The email settings area can be open and closed using the Email settings button.

Subject line

Enter a subject line for your email.

Optimize your subject line

There are strategies that you can use to improve your subject lines and avoid your messages being marked as spam. The following are best practices for creating email subject lines:

• Use well-constructed subject lines, which can have a huge impact on open rates.
• Keep them specific to the email theme and messaging, don't use gimmicks.
• Use personalization in subject lines.
• Keep subject lines short but meaningful.

Some subject lines cause ISPs and email clients to filter emails out or send them to spam. You should avoid these phrases and symbols to ensure that your customers receive your emails. The following examples are commonly used phrases that ISPs and email clients filter out.

The following examples are other problematic phrases that can trigger spam filters or add spam points.

To avoid triggering spam filers, avoid the following items in your email subject lines.

• Quotation marks, dollar signs, and exclamation points
• All capital letters (shouting)
• A toll-free number
• A font size larger than 2+

You can also personalize your subject line. However, you must select a contact source first. For more information what you can include in subject lines, refer to Symbols and special characters.

Address settings

Every email must include a From name, From address, and Reply-to address. By default these fields are populated with the information stored in the user profile of the email creator, but they can be edited for each email.

The administrator can change the settings for individual users.

1. Go to Settings > User accounts.
2. For each user, provide values for the email address defaults.

Users can change their own settings.

1. Go to Settings > User profile.
2. Provide values for the email address defaults.

Contacts

Select a database, contact list, or query for the email, excluding seed lists. All emails, except for tests and autoresponders, are automatically sent to the seed list.

Click Select Contacts or Change. Select your source, then click Done.

To calculate the size of the contact source, click the send count icon next to About contact source. While the count is calculated, you can continue working on the email.

Note: Blank email records will not be included in the count.

Email settings

In email settings you can set tracking level, add tags, choose message encoding and more. Mailing notes are not visible to contacts who receive the email.

You can choose one of four tracking levels, depending on what information you want to collect:

• To track everything down to the unique email address (including opens, clicks, forwards, and subscribes), select Unique.
• To collect grand totals on the tracking metrics, select Aggregate.
• To track only the opened mailings, select Opens Only.
• To track only information on bounces, select No Tracking.

Sent emails are tracked when images in an email are downloaded and viewed. Campaign uses a 1x1 pixel that is placed in emails to determine whether it was opened. If images aren't viewed by the recipient, because they either block all images or receive a text-only email, then the tracking pixel isn't triggered and the email isn't tracked.

The third-party tracking pixel doesn't affect any reports when retrieved. Tracking behaves the same way as the tracking pixel.

Warning: Inserting a tracking pixel into the email may not work correctly with minified code.

Tags for email

Email tagging helps you quickly search for specific messages. For example, you can tag a group of databases and emails as “Easter campaign.” 

Note: There is a limit of 700 tags (4,000 characters) per org.
