EonMailer Usually far cheaper than Mailchimp × N
Stack SES pennies-per-thousand with one EonMailer plan. Ten client lists on per-contact ESPs can run hundreds to $1,000+/mo — Growth + modest SES volume is often closer to ~$120 in the same ballpark example.
For agencies that run email for many clients
The email operations console for digital agencies
Built for digital agencies running email for about 5–40 clients
One desk for every brand you manage: workspaces, campaigns, approvals, deliverability, automations, forms, and white-label reports. Clients keep their SES, SendGrid, Mailgun, or SMTP — you get the ops layer, not another ESP with per-contact pricing.
Replace N Mailchimp logins and Slack approvals with one agency console — usually far cheaper at scale.

The agency reality
You’re not missing charts. You’re drowning in context switches.
Most agencies already “do email.” The tax is operational: wrong login, wrong brand, approval in WhatsApp, report as a screenshot, SES too hard, Mailchimp too expensive at N clients.
Without EonMailer
- Separate ESP login per client
- Copy reviews scattered across Slack / Docs
- Per-contact pricing × every brand
- Domain setup tribal knowledge
- Monthly proof = PDF collage
- “Which client am I in?” all day
With EonMailer
- One agency desk, workspace switcher
- Review links + status that move work
- BYO provider — ESP bills stay theirs
- Guided readiness before send
- Shareable packs under your brand
- AM always scoped to the right client
Before logos
What agency teams tell us they’re escaping
Not customer reviews — patterns from owners and AMs evaluating a multi-client desk. When design partners publish quotes, they’ll live here with names.
“Which Mailchimp is this?”
“We’re paying per contact × every retainer.”
“Approvals live in WhatsApp. There’s no audit.”

Why agencies pay
Outcomes, not feature theater
Always know which client you’re in
A workspace switcher scopes campaigns, contacts, deliverability, and reports. Account managers stop guessing which login is live.
Approvals leave Slack
Named reviewers, client review links, and a clear ready-to-send path — with an audit trail instead of WhatsApp archaeology.
Send only when deliverability is ready
Domain, sender, and webhook readiness gate sends before launch. Fewer “why did this bounce?” emergencies.
Time to first send
Up and running without a six-week project
The product is aimed at a short path: desk → client → provider → ship. That’s how agencies judge software.
1 Create the agency desk
Sign up free — no card. Invite your first teammate when you’re ready.
2 Add a client workspace
One brand, one scope. Campaigns and contacts never leak across retainers.
3 Connect their provider
SES, SendGrid, Mailgun, or SMTP. Guided readiness until a safe test send is possible.
4 Ship with approvals + proof
Pipeline, client review links, then share branded reports when the month closes.
White-label proof
Client packs that look like you — not the ESP
Shareable report links and PDFs under your agency brand — watch the full pack scroll through below, then open the real file.

Built for trust
Professional ops without the theater
No fake logo walls. These are the guarantees the product is designed around.
Client data isolation
Workspaces wall off contacts, campaigns, and providers so brands don’t bleed into each other.
You keep the ESP relationship
BYO sending means reputation and send invoices stay with the client’s provider — not a hidden markup.
Owner-only billing
Plan changes are gated to the agency owner. Ops roles ship work; they don’t touch the card.
Send gates before launch
Deliverability readiness can block a bad send with a clear fix path — not a post-bounce autopsy.
FAQ
Questions agencies ask before signing up
Can I use my clients’ Amazon SES, SendGrid, or Mailgun accounts?
Yes. EonMailer is bring-your-own-provider (BYO). Each client workspace connects its own SES, SendGrid, Mailgun, or SMTP account so send cost and reputation stay with them — not on a shared ESP you mark up.
Is EonMailer another Mailchimp or ESP?
No. We are the agency ops console: workspaces, approvals, deliverability, automations, forms, and white-label reports. Clients keep their sending infrastructure; you run the process from one desk.
Why do agencies choose SES with EonMailer?
SES is often pennies per thousand emails, but raw AWS is hard for account managers. EonMailer adds guided setup, readiness gates, multi-client switching, and reporting so SES becomes usable at agency scale.
Can each client use a different provider?
Yes. One brand on SES, another on SendGrid, another on SMTP — each workspace is isolated. Resend, Brevo, and Postmark are on the roadmap.
Where do I learn SES / SendGrid / Mailgun setup?
Step-by-step guides live on our Help Center (https://help.eonmailer.com), covering create-account, API keys, domain DNS, and connect-to-EonMailer for each live provider.
