Single Sends

Twilio SendGrid Single Sends use our Design and Code Editors, allowing you to build templates and customize your designs. Twilio SendGrid also provides a library of pre-built designs that you can duplicate and modify.

See our dedicated Design and Code Editor page for more on working with email designs.

After creating multiple Single Sends, you can modify and delete them as needed. To make managing multiple Single Sends easier, Twilio SendGrid offers search functionality, enabling you to find a Single Send quickly by name.

You can also filter your search results by status — "Draft," "Scheduled," or "Triggered" — and any categories you have added to your Single Sends.

When filtering by multiple categories, Marketing Campaigns will return results matching any of the categories specified. For example, if you filter by the categories "Newsletter," "Promotion," and "BOGO," Marketing Campaigns will return Single Sends matching one or more of those categories.

A/B testing, also known as split testing, is an effective way to test different versions of your email to improve customer engagement. A/B tests allow you to create multiple versions of a Single Send and deliver each to a subset of your audience. Based on the performance of each variant, a winner is selected that can be sent to the rest of your contacts.

When working with A/B tests, you can

• Clone variations of A/B tests
• Delete variations of A/B tests
• Manually select the winner of an A/B test

See our dedicated A/B Testing page to learn how to create and manage your A/B tests.

You can exclude up to 5 segments and 50 lists from a Single Send. Twilio SendGrid will omit any contacts who are on one of your excluded segments or lists from the send.

Single Sends are integrated with Twilio SendGrid's Email Testing feature. Email Testing allows you to check not only whether or not your messages will be rendered properly across mail clients but also how likely a message is to perform well across spam filters.

For more about testing, see our dedicated Email Testing page.

To manage your Single Sends programmatically, use the Twilio SendGrid Single Sends API.

1. Go to Marketing and select Single Sends.
2. Click Create Single Send.
3. Select a template from Your Email Designs or one of the pre-built SendGrid Email Designs. For more information about pre-built designs, see Working with Marketing Campaigns Email Designs.

To create a template from an existing Single Send, select the action menu next to the email you'd like to reuse and select Create Template.

4. Select an editor. You can choose between the Design Editor and the Code Editor:
   • Inside the Design Editor, the Settings, Tags and Build tabs allow you to design and configure your email.
   • Inside the Code Editor, you can click the left Settings tab to expand the settings window, and then you can configure your email using the Settings and Tags tabs.
5. Click Save. Your Single Send is now created.

Next, edit the Single Send's settings.

The Single Send Settings tab allows you to configure all the essential information about your Single Send, including the sender and recipients. To completely prepare a Single Send's settings, you must define the following fields.

• From Sender: The publicly visible sender of your Single Send. This email address should be one of your verified senders. See our sender verification documentation for more information about setting up a verified sender.
• Email Subject: The email's subject line. This field can be A/B tested.
• Recipients: The segments or lists you want to send the email to.

• Scheduling: A Single Send can be sent immediately or scheduled in advance. If you select Specify a Date and Time, Date and Time fields will be displayed where you can set a future send time.

In addition to the settings necessary to send your messages, Single Sends provide optional settings that allow you to more precisely manage how you target your audience with each message.

You can exclude specific segments or lists from your Single Send.

1. Go to Marketing and select Single Sends.
2. Create a new Single Send or open existing Single Send.
3. In the Single Send Settings tab, under Recipients , toggle Exclude specific recipients to ON .
   Expand image
4. Select the lists or segments to exclude from the Single Send. You can include as many as 5 segments and 50 lists.

The contacts associated with your selected lists or segments will be excluded from the Single Send.

If you have dedicated IPs, you can set up IP Pools that allow you to separate your traffic and potentially enhance your deliverability by protecting your sender reputation.

To use IP pools for Single Sends, go to Single Send Settings and select the IP pool from the IP Pool menu.
