About SendGrid
Where your transactional mail really lives.
SendGrid was founded in 2009 in Denver by Isaac Saldana, Jose Lopez and Tim Jenkins to solve one specific problem: developers trying to send email from their own servers kept ending up in the spam folder. The company went public on the New York Stock Exchange in November 2017 and was acquired by Twilio in February 2019 for roughly two billion dollars, where it now runs as Twilio's email division. According to its own numbers it delivers more than 100 billion emails every month across the platform.
The product is not a newsletter tool. SendGrid is primarily the Email API that applications call when a user resets a password, a webshop confirms an order, a billing system fires a receipt or a SaaS product nudges a failed login. The Marketing Campaigns module exists on top of the same infrastructure, but the centre of gravity is transactional: the message that has to arrive within sixty seconds of the event that triggered it, on the right device, without landing in the spam folder. The point of pulling SendGrid into a warehouse is that its statistics, bounce logs, block lists, spam-report feeds and suppression tables describe a different reality from the marketing dashboard: sender reputation, time-to-inbox, template-level deliverability and the IP-warmup state that decides whether next Tuesday's order confirmation arrives at all.
