Lettr.com

Lettr gives SaaS teams one place to manage and understand all the emails their app sends. Use it for transactional emails like onboarding, password resets, trial reminders, invoices or product notifications. You get a simple overview of what is being sent, to whom, how often, and how each email performs over time — without digging through message logs, tags and analytics dashboards. Templates can also be managed directly in Lettr, so product and marketing teams can update email content without changing application code. We built Lettr after running several SaaS products ourselves and realizing we were missing exactly this overview. Our team has been working in email infrastructure, deliverability and email security for 10+ years.
