Frequently Asked Questions
Q1: Is AWS SES suitable for startups?
Yes. SES scales seamlessly from a few hundred to millions of emails with minimal configuration.
Q2: Does using Postal impact deliverability?
No, deliverability still depends on SES. Postal only manages submission and tracking.
Q3: Can I use the same domain for marketing and transactional mail?
Technically yes, but it’s risky. Use subdomains (mail.domain.com) to separate reputation.
Q4: How can I monitor bounce and complaint rates in SES?
Set up SES event publishing through SNS → CloudWatch → Grafana or your existing monitoring stack.
Q5: What’s the typical ROI difference between SES and SaaS?
At 1.2M emails/month, SES costs ~$120; SaaS typically costs $1,200–1,500 — about a 10× difference.
