What Twilio SendGrid is, in short
SendGrid (now Twilio SendGrid) is a leading email delivery platform competing with Mailgun, Amazon SES, and Postmark in the transactional email space, and with Mailchimp and Brevo for marketing email. Acquired by Twilio in 2019, it serves as the email infrastructure layer for applications needing reliable, high-volume email delivery with deliverability optimization. SendGrid's strength is its scale and deliverability expertise — it processes over 100 billion emails monthly with sophisticated IP reputation management, authentication (SPF, DKIM, DMARC), and deliverability consulting for higher tiers. The platform supports both transactional emails (password resets, receipts) and marketing campaigns with a drag-and-drop editor.
Ideal customers are SaaS companies and marketplaces that need reliable transactional email at scale plus basic marketing email capabilities. Buyers should evaluate SendGrid against Mailgun for developer-focused transactional email (Mailgun offers more flexible inbound parsing), against Amazon SES for raw cost at very high volumes, and against Postmark for deliverability-obsessed transactional-only use cases. The marketing email features are functional but less sophisticated than dedicated platforms like Klaviyo or Brevo — if marketing automation is primary, consider those instead.
