SendGrid (part of Twilio) is the world's most widely used email delivery platform, trusted by more than 80,000 companies to send transactional and marketing emails at scale. For RevOps teams, SendGrid provides the sending infrastructure that powers product notifications, automated email sequences, and marketing campaigns — with industry-leading deliverability and detailed email analytics.
Product Overview
SendGrid operates two core products: the Email API for developer-driven transactional email sending, and Marketing Campaigns for no-code email programme management. Its deliverability infrastructure handles IP reputation management, DKIM/SPF configuration, bounce processing, and unsubscribe management automatically — so teams can focus on content rather than technical email plumbing. The Expert Insights dashboard provides real-time deliverability monitoring, inbox placement rates, and engagement analytics across every IP and domain in use.
Key Features
- Email API: RESTful API for sending transactional emails programmatically — with SMTP relay option and client libraries for all major languages.
- Marketing Campaigns: No-code email builder for creating, sending, and A/B testing marketing emails to segmented contact lists.
- Deliverability Insights: Real-time inbox placement rates, bounce analysis, and reputation monitoring across all sending domains and IPs.
- Dedicated IPs: Dedicated IP addresses for high-volume senders who want full control over sender reputation.
- Email Validation API: Real-time email validation endpoint to reduce bounces and protect sender reputation at the point of collection.
