A Single Send is a one-time non-automated email message delivered to a list or segment of your audience. You can schedule a Single Send or send it immediately. Unlike an Automation, a Single Send is not part of a series of related messages that are designed to work in sequence.
Single Sends can be used to deliver promotional offers, engagement campaigns, newsletters, announcements, legal notices, policy updates, and more.
Twilio SendGrid Single Sends leverage our Design and Code Editors, allowing you to create templates quickly and easily without sacrificing the ability to 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 a powerful way to optimize engagement with your email. 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
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.
For those who want to manage their Single Sends programmatically, Twilio SendGrid provides the Single Sends API.
To create a new Single Send
You can also create a template from an existing Single Send by selecting the action menu next to the email you'd like to reuse and selecting Create Template.

The 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.
There is a limit of 10 segments per Single Send.
See our segmentation documentation for more information about managing your contacts and building Single Sends based on engagement data.
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.
To exclude a segment or list from your Single Send
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.
