What reviewers say
Flexible Single Email API That’s Easy to Edit and Trigger
“Single Email API works great. It’s flexible, and it’s easy to edit and trigger when I need it.”
Reliable and very fast API to run email campaigns
“I love the SendGrid Logic Apps connectors; they make integration smooth and very easy to use. It’s also very flexible to use HTTP requests when I need dynamic templates, and the API spec documents are easy to read and very intuitive. The system performance is great: I’ve run mail”
Scalable and Easy to Use, Reliable Email Delivery at a Fair Price
“Twilio SendGrid is easy to use and a complete solution. I am confident in the performance and that my emails will be delivered as they should. The pricing is fair, especially for a startup. The signup process is easy and you can get up and running in no time.”
