Amazon SES and developer infrastructure
Amazon SES API credentials vs SMTP credentials
Avoid the common mistake of using one credential type in the other interface.
Avoid the common mistake of using one credential type in the other interface. The safest starting point is to understand who controls the domain, what people need from email each day, and which parts must keep working while the change is made. Amazon Web Services, Amazon Web Services
A simple plan you can follow
Work through these steps in order
- 1
Identify the interface
Check whether the application calls the AWS API or connects to an SMTP hostname.
- 2
Create a dedicated identity
Use least privilege and never enter an AWS root credential.
- 3
Match the region
Use the endpoint and verified identity from the same SES region.
- 4
Test safely
Send to a controlled recipient and record the provider response before production use.
| Option | Good choice when | Check before deciding |
|---|---|---|
| Keep the current setup | The problem is temporary and the present provider still meets the team's daily needs | Confirm the same failure will not return after the immediate fix |
| Amazon SES | Its specialist features matter more than a simpler mailbox and migration experience | Check pricing, support, exports and the exact amazon ses smtp credentials requirement |
| Venmail | The team wants custom-domain mail, guided setup and a clear migration path | Choose another provider when a full office suite or infrastructure-only API is the main need |
Before you call the job finished
- API and SMTP credential types are not mixed
- Root credentials are not used
- The region matches
- Secrets have an owner
- Rotation and revocation are documented
A founder may work in one country while the AWS account is operated elsewhere. Record the account owner, region and emergency contact so credential problems do not depend on one unavailable person.
