Which AWS SES region should I choose?
Pick one region Meisa supports, close to you or where your data must stay, and do everything in it: domain, production access and keys.
On this page
Pick one region and use it for everything: verifying your domain, requesting production access, and the Region you choose in Meisa. If you have no strong reason, use US East (N. Virginia) (us-east-1). If you need your sending data to stay in the EU, use Europe (Ireland) (eu-west-1) or Europe (Frankfurt) (eu-central-1).
Why the region matters
In Amazon SES, almost everything is separate per region:
- Domain identities. A domain verified in us-east-1 is not verified in eu-west-1.
- Sandbox and production access. Production access is approved for one region at a time. Moving to a new region means a new request.
- Sending quota. Your daily limit and per-second rate are set per region.
- Configuration sets and SNS topics that Meisa creates for delivery tracking live in the region you connected.
So if your keys say one region and your domain is verified in another, Meisa will not see the domain and sending will fail.
Regions you can choose in Meisa
The Region list in the Connect Amazon SES form offers:
| Region name | Code |
|---|---|
| US East (N. Virginia) | us-east-1 |
| US East (Ohio) | us-east-2 |
| US West (N. California) | us-west-1 |
| US West (Oregon) | us-west-2 |
| Europe (Ireland) | eu-west-1 |
| Europe (London) | eu-west-2 |
| Europe (Frankfurt) | eu-central-1 |
| Asia Pacific (Mumbai) | ap-south-1 |
| Asia Pacific (Singapore) | ap-southeast-1 |
| Asia Pacific (Sydney) | ap-southeast-2 |
| Asia Pacific (Tokyo) | ap-northeast-1 |
If your SES account is set up in a region that is not on this list, email [email protected] before you start.
How to choose
- Already using SES? Use the region where your domain is already verified and production access is approved. Check it in the SES console: the region name is shown at the top right, and Account dashboard says whether you are in the sandbox there.
- Data rules. If your customers or your contract require EU processing, pick an EU region.
- Otherwise, pick us-east-1. It is the default in Meisa and AWS launches SES features there first.
Delivery speed to inboxes is not noticeably different between regions, so do not overthink this.
How to check and switch the region in the AWS console
- Open the SES console (type “SES” in the AWS search bar and choose Amazon Simple Email Service).
- Click the region name at the top right of the console, next to your account name.
- Choose your region. Every SES page you open now applies to that region.
Changing region later
- In the new region, request production access and wait for approval.
- In Meisa, open Email setup, click the More actions menu (three dots) on your SES provider and click Edit.
- Change Region and click Save changes.
- Right away, before sending anything, open the More actions menu again and click Set up delivery tracking. Meisa creates the tracking configuration set in the new region. Until you do this, sends can fail because the old region’s configuration set does not exist in the new one.
- In the Domains section, click View records on your domain, then Refresh records. Meisa adds the domain to SES in the new region and shows its new DKIM records.
- Add the new DKIM records at your DNS host (the old ones can stay). AWS verifies the domain in the new region once it sees them, often within an hour. You can confirm it in the SES console under Identities, with the new region selected. See Add Meisa’s DNS records at your DNS host.
Plan the switch for a quiet time: until the domain verifies in the new region, your senders cannot send.
