Automated MailerSend Delivery Reconciliation
Every Monday, WebRun opens MailerSend, reads the sent, delivered, and bounced counts for each sending domain over the past week, logs the numbers as a record in Airtable, and emails the developer lead through Gmail whenever the delivered count falls short of sent by more than a small margin.
How do I reconcile MailerSend sent and delivered counts?
Every Monday, WebRun reads MailerSend's sent, delivered, and bounced counts for each sending domain, logs the numbers as an Airtable record, and emails the developer lead through Gmail whenever delivered falls short of sent by more than a small margin. Delivery problems get caught within a week instead of surfacing from a customer complaint.
- Delivery gaps get caught within a week instead of from a complaint
- A running Airtable history tracks delivery health over time
- The developer lead only hears about it when a gap is real

Connect once, stays signed in
WebRun signs in once and keeps each session in a persistent environment, so every run picks up right where it left off.
Every action is checked against this policy before it runs.
Questions, answered
Does it resend anything that failed to deliver?
No. WebRun only reports the gap between sent and delivered. Investigating or resending stays a decision for the developer lead.
What counts as a real gap?
A delivered count meaningfully below sent, beyond the small margin every sending domain normally sees from routine bounces.
What if there is no gap that week?
No email goes out. The Airtable record is still logged so the clean week is part of the running history.
