The short version

  • Only Keila has a free tier, so it costs nothing to try first.
  • Each has a real cost: Amazon SES there is no campaign UI, template editor, list management or scheduling interface at all, so any marketer-facing use case requires building or buying a separate application on top of the raw API.; Keila there is no free hosted plan at all, stated as deliberate policy, so unlike almost every competitor there is no way to run a small list at zero cost without self-hosting it yourself.
  • They diverge on capability: Amazon SES covers Send and receive API, Keila covers Priced by emails sent.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

The jobs each tool is most often brought in to do.

  • An agency running several separate client lists that does not want to pay per project or per additional listnot Amazon SES

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Amazon SES

  • There is no campaign UI, template editor, list management or scheduling interface at all, so any marketer-facing use case requires building or buying a separate application on top of the raw API.
  • Deliverability and sender reputation management are the sender's responsibility to configure correctly; a mistake in DKIM, SPF or DMARC setup has no support layer catching it before it affects deliverability.
  • New accounts start in a sandbox with strict sending limits and must request production access from AWS, adding a manual approval step some competitors do not require.
  • Inbound email processing via Mail Manager is priced and configured separately from outbound sending, so a bidirectional email use case is really two separate services to set up.
  • Comparing its per-message price directly against Campaign Monitor or Zoho Campaigns is misleading, since those prices include a full marketing platform that SES does not provide at any price.

Keila

  • There is no free hosted plan at all, stated as deliberate policy, so unlike almost every competitor there is no way to run a small list at zero cost without self-hosting it yourself.
  • Marketing automation is minimal, with none of the behavioural triggers, journey builders or e-commerce revenue attribution that Klaviyo, Brevo and Mailchimp treat as table stakes.
  • The self-hosted route puts deliverability entirely on you: reputation, SPF, DKIM, DMARC, warm-up and bounce handling are your problem, and a badly configured instance will land in spam folders.
  • It is a small project from a small company, so the integration ecosystem is thin and there is no partner network, template marketplace or large body of community expertise to draw on.
  • Email volume tiers step in fixed blocks, so an organisation whose sending is uneven across the year either overbuys at the annual peak or has to change plan repeatedly.

Answered from the vendors’ own pages

Amazon SES: Can I use SES for marketing campaigns like Campaign Monitor?

Technically yes via the API, but there is no campaign UI, segmentation tool or template editor; you would need to build or buy that layer separately.

Keila: Is Keila free?

The software is, under AGPL-3.0-or-later, if you self-host. The hosted service has no free plan by deliberate policy and starts at 8 EUR a month.

Amazon SES: Is there a free tier?

New AWS customers can access AWS Free Tier credits usable against SES for a limited period, but there is no permanent free sending allowance.

Keila: How is the hosted service priced?

By emails sent, from 8 EUR for two thousand up to 256 EUR for two hundred and fifty thousand a month. Contacts and projects are unlimited on every tier.

Amazon SES: Why is it so much cheaper per email than a marketing platform?

Because it sells only the sending infrastructure; the price excludes every campaign management feature a marketing platform bundles into its per-email cost.

Keila: Can I use my own email provider?

Yes. AWS SES, Sendgrid, Mailgun, Postmark, generic SMTP or a personal inbox are all supported as sending backends.

Keila: Are there discounts?

Pentacent offers reduced rates to nonprofits and open source projects on request.
