SendGrid (now part of Twilio) handles transactional and marketing email at scale. Reliable delivery, good APIs, but the UI and marketing features lag behind dedicated email marketing tools.

Slack is the dominant workplace messaging platform with channels, threads, integrations, and workflows. It replaced email for millions of teams but can become a notification nightmare.
Reviewer scorecard
“Transactional email API is rock-solid. Event webhooks for delivery tracking are essential. The standard choice for SaaS apps.”
“Essential for dev teams. GitHub, CI, and alerting integrations make it the nervous system of any engineering org.”
“Deliverability is good and the API is simple. Don't bother with their marketing features though — use Mailchimp for that.”
“It's bloated and expensive at scale, but there's no real alternative that matches its ecosystem. Reluctant ship.”
“The email template builder is basic compared to Mailchimp or ConvertKit. Stick to it for transactional email only.”
“Canvas, clips, and huddles have made it more than just chat. Great for async creative collaboration.”
