EonMailer The agency pain
Raw SES is powerful but account managers drown in IAM, sandbox limits, DNS, and “which AWS account is this?”

Amazon SES for agencies — without the AWS chaos
SES is the cheapest serious sending infrastructure for agencies. EonMailer makes it operable across 5–40 clients — workspaces, approvals, and deliverability gates included.
What EonMailer adds
Connect each client’s AWS credentials, validate sandbox vs production, guide domains/senders, and auto-wire event tracking when permissions allow.
Outcome
You sell agency process on SES economics — not a per-contact SaaS tax × N brands.
Capabilities
Amazon SES with EonMailer
- BYO SES per client workspace — reputation isolation
- Validate credentials + sandbox/production quota on connect
- Domain & sender readiness before first campaign
- Opens, clicks, bounces via Configuration Set + SNS when tracking is set up
- Agency approvals, automations, forms, and client report packs on top
Setup path
From zero to first safe send
- Create or pick the client’s AWS account and leave SES sandbox when ready
- Create an IAM user with the send + identity permissions EonMailer lists
- Connect SES in Deliverability → guided setup for that workspace
- Authenticate the sending domain and confirm event tracking
- Send a test, then run campaigns from the agency desk

FAQ
SES questions agencies ask
Is EonMailer an Amazon SES reseller?
No. You (or your client) keep the AWS account and SES bill. EonMailer is the agency operations layer that connects to that account.
Can I use one SES account for many clients?
Technically possible, but we recommend one provider connection per client workspace so reputation and billing stay clean. Most agencies use a dedicated AWS account or IAM scope per brand.
What if the client is still in the SES sandbox?
EonMailer surfaces sandbox limits during validate/connect. You can still set up DNS and verified identities; production sending waits on AWS approval.
How does SES pricing compare to Mailchimp for agencies?
SES is typically ~$0.10 per 1,000 emails after free tier. Mailchimp-style tools charge per contact per brand. Stacking SES with one EonMailer plan is usually far cheaper at multi-client scale.
