Identifying connection issues involves monitoring various metrics and using specialized tools:
Bounce Rates: A high bounce rate can indicate issues with invalid email addresses or server problems. Open Rates: Low open rates might suggest that your emails are being filtered into spam folders. Delivery Reports: Utilize delivery reports from your email service provider to track the status of your sent emails. Email Authentication: Ensure that your emails pass through authentication protocols like SPF, DKIM, and DMARC.
