General
SendGrid provides a cloud-based service that assists businesses with email delivery.[7][9][20][21] The service manages various types of email including shipping notifications, friend requests, sign-up confirmations, and email newsletters. It also handles Internet service provider (ISP) monitoring, domain keys, the sender policy framework (SPF), and feedback loops.[13][22][23][24] Additionally, the company provides link tracking and open rate reporting.[22] It also allows companies to track email opens, unsubscribes, bounces, and spam reports.[7][22][25]
Beginning in 2012, the company integrated SMS, voice, and push notification abilities into its service through a partnership with Twilio.[15]
SendGrid offers a freemium version and a Lite Plan (pay-as-you-go), as well as three expanded levels of service: Essentials, Pro, and Premier.[7][26][27]
SendGrid's clients include Uber, Twilio, Foursquare, Pandora, and Airbnb.[13][21][24][28]
