Frequently Asked Questions

Everything you need to know about email infrastructure

Clear, transparent answers on deliverability, API authentication, and rate limits.

AWS SES requires complex IAM permissions, SNS/SQS bounce wiring, manual dedicated IP warm-up, and support tickets to exit the sandbox. SadaSend provides production sending in 2 minutes with automated deliverability.
