The short version

  • Only Instantly 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.; Instantly shared mailbox rotation could expose sender reputation to other users' poor practices; domain reputation can degrade rapidly if co-users violate sending norms

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.

Instantly

  • Shared mailbox rotation could expose sender reputation to other users' poor practices; domain reputation can degrade rapidly if co-users violate sending norms
  • AI campaign generation, whilst useful, produces generic copy; personalisation still requires manual review and editing for high-quality outreach
  • Email as primary channel faces declining effectiveness; spam filtering improves and email open rates decline generally
  • Lead database quality varies; verification filters may miss invalid addresses or outdated contacts
  • Freemium model limits features significantly; advanced analytics, API access, and priority support require paid tiers

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.

Instantly: Is Instantly free?

Instantly offers a freemium model. No credit card is required to start. Free tier includes basic lead finding and campaign creation; paid tiers unlock advanced features (API access, advanced analytics, priority support).

Source
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.

Instantly: How does Instantly's AI Copilot work?

AI Copilot generates email copy, subject lines, and follow-up sequences based on brief campaign descriptions. Users can customise generated templates before sending.

Source
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.

Instantly: What CRMs does Instantly integrate with?

Instantly integrates with Salesforce, HubSpot, Pipedrive, and Zapier. Custom integrations via REST API are available on paid plans.
