Email API Frequently Asked Questions
How does Twilio SendGrid work?
Twilio SendGrid is a cloud-based SMTP provider that acts as an email delivery engine, allowing you to send email without the cost and complexity of maintaining your own email servers. Twilio SendGrid manages the technical details of email delivery, like infrastructure scaling, ISP outreach, reputation monitoring, and real-time analytics.
Do I have to sign up for the Marketing Campaigns and Email API separately?
Yes! If you want to use Marketing Campaigns and the Email API, you will need to purchase the plans separately. But once you sign up, you can use the same account to send via the Email API or through Marketing Campaigns.
If you send more emails than your plan allows within a given billing period, you will be charged a small overage fee on a per-email basis. Any overage fees are added to your invoice for the following billing period.

You can also work with our Delivery Consultants to evaluate your entire email program and get a detailed assessment to help you identify areas for optimization, such as configuring your IPs correctly or diagnosing email deliverability issues.
