SendGrid

Say goodbye to email fire drills by building and monitoring your email solution on a trusted foundation. Our Email API and purpose-built MTA send over 100B emails per month for businesses of all sizes. On our collaborative platform, your teams can work together to create email templates that send programmatically, analyze email performance, and troubleshoot diagnostically to identify delivery issues.

Getting your emails delivered is our #1 priority - we understand that lost emails are lost customers. Our email platform provides streamlined tools and recommendations to achieve optimal inbox placement. With infrastructure that automates queue handling and throttles threat detection, Twilio SendGrid enables your teams to focus on building innovative customer experiences by optimizing for deliverability, scalability, and security.

Use Cases

• Create personalized promotions based on triggers and segmentation.
• Optimize email marketing campaigns with automation and intelligence.
• Connect with consumers at the perfect time to influence a purchase, improving customer loyalty and lead conversions.

Account Setup

Two Factor AuthenticationTwo-factor authentication (2FA) is required by Twilio SendGrid in order to protect senders from account takeovers. To enable 2FA, navigate to Settings > Two-Factor Authentication in the Twilio SendGrid App, and click Add Two-Factor Authentication. To learn more about setting up 2FA, please read the documentation.

API KeysAPI Keys are used by your application, mail client, or website to authenticate access to Twilio SendGrid services. Unlike a username and password, an API key can be scoped to provide access to the minimum services needed by your application, and you can revoke an API key at any time without needing to change your username and password. For these reasons, API keys are required when connecting to all of Twilio SendGrid’s services. To learn more about creating API keys, please visit the Twilio SendGrid Knowledge Center.
