The short version

  • Only Omnisend 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.; Omnisend free plan caps at 250 contacts and 500 emails per month

What people use each for

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

Amazon SES

  • An engineering team sending transactional email (receipts, password resets, alerts) at a volume where per-message cost dominates the decisionnot Omnisend
  • A company building its own email product or newsletter tool on AWS and wanting to own the campaign layer itselfnot Omnisend
  • A business already deep in AWS infrastructure wanting to avoid adding a separate marketing-platform vendor for pure transactional sendingnot Omnisend
  • A high-volume sender for whom SES's per-thousand rate is materially cheaper than a marketing platform's equivalent volume pricingnot Omnisend

Omnisend

  • Sending cart abandonment recovery emails with product recommendationsnot Amazon SES
  • Segmenting customers by purchase history for targeted SMS campaignsnot Amazon SES
  • Creating browse abandonment sequences triggered by browsing behaviornot 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.

Omnisend

  • Free plan caps at 250 contacts and 500 emails per month
  • Standard plan is limited to 500 contacts and 6,000 emails per month before an upgrade is required
  • SMS is billed separately starting at $0.007 per message and varies by country and volume
  • Custom pricing only begins above 150,001 contacts, requiring a sales conversation at that scale
