help SendGrid FAQ
Is SendGrid better for transactional email or marketing newsletters?
SendGrid is strongest as a transactional email API for receipts, password resets, signup confirmations, and product notifications. It also has marketing campaign tools, but many developers choose it first because of its API, SMTP relay, templates, bounces, and suppression handling.
What is the Twilio connection with SendGrid?
Twilio announced the SendGrid acquisition in 2018 and completed it in 2019. That is why the product is often branded as Twilio SendGrid and sits alongside Twilio's SMS, voice, and customer engagement tools.
Can SendGrid handle both API sending and SMTP sending?
Yes, SendGrid supports both a Web API and SMTP relay. The API is usually better for application code, while SMTP can be easier when plugging into older apps or platforms that already expect SMTP settings.
How does SendGrid fit against Mailgun, Postmark, or Amazon SES?
SendGrid competes directly with Mailgun and Postmark for developer-focused email delivery, while Amazon SES is usually the lower-level AWS option. SendGrid's advantage is the packaged dashboard, templates, analytics, and deliverability tooling rather than the lowest possible raw send cost.
