The trade-offs

Strengths and Limitations

Amazon SES

Strengths

Per-message pricing with no seat licence and no monthly fee on the à la carte rate
SMTP interface and SES v2 API, callable from the AWS SDKs and the CLI
Inbound mail can land in S3, publish to SNS or trigger Lambda functions
Up to 20,000 stored templates per region, or inline templates supplied per request
Shared, managed dedicated or bring-your-own IP addresses
Sending rates fall at 10 million and 100 million emails per month

Limitations

No campaign editor, journey builder or drag-and-drop template designer
The Pro and Enterprise fixed fees are charged per account and per region
Deliverability tooling is a separately priced add-on, Virtual Deliverability Manager
Running it in practice means operating SNS, Lambda, CloudWatch and IAM alongside it
A failed call to a multi-recipient message rejects the whole email, so AWS recommends one recipient per call
Attachment data is billed separately at $0.12 per GB

Twilio SendGrid

Strengths

Transactional and marketing email on one account, so both build the same sender reputation
Deliverability tooling included: dedicated IPs, domain authentication, SPF, DKIM and DMARC, plus inbox rendering and spam tests
SDKs for Python, Ruby, Go, PHP, Java, C# and JavaScript, alongside SMTP relay and event webhooks
Real-time and bulk email address validation

Limitations

Email only, other channels mean buying a separate Twilio product
Automation in Marketing Campaigns requires the Advanced plan
The free offering is a 60-day trial, not a standing free tier
Two separate price ladders to compare, one per product
