How do you analyse Sendgrid / Postmark / SES emails into groups and funnels
I'm curious how people running real SaaS/products handle this.
Say you're sending transactional/product emails through SendGrid:
\- welcome email
\- onboarding day 1 / day 2 / day 3
\- password resets
\- invitations
\- billing emails
\- notifications
How do you actually understand how these emails are performing?
Not just "was this particular email delivered?"
I mean things like:
\- Which email types are performing best/worst?
\- What's the funnel through Welcome → Day 1 → Day 2 → Day 3?
\- Where are users dropping off?
\- How do different signup cohorts compare?
\- Opens/clicks by email type
\- Which links are being clicked
\- Device / client breakdown
\- Country / geography
\- Gmail vs Outlook etc.
\- Performance over time
\- Ultimately, whether people who engage with an email actually do the thing the email was meant to make them do
Marketing ESPs give you a lot of this for campaigns and automations.
But if your product sends email directly through Sendgrid, what do you use?
Do dashboards give you enough?
Do you pipe all the events into PostHog/Amplitude/BigQuery and build it yourself?
Did you build an internal dashboard?
Or do you mostly just not analyse transactional emails at this level?
Would particularly love to hear from anyone sending enough email that this has become a real problem.
