|---|---|---|
| Pricing basis | Flat platform subscription; AWS delivery usage separate | Subscribed-contact tiers; paid plans include unlimited sends |
| Entry plan | Free platform plan; SES usage billed by AWS | Free up to 1,000 subscribed contacts and 4,000 sends per rolling 30 days |
| Workflow tools | Visual canvas, SendFlow, API, and MCP | Loop builder plus API and agent tooling |
| Sending account | Your own AWS SES | Managed through Loops |

Put the workflow to the test
Evaluate a first-project onboarding journey
Welcome a signup, wait for the first project, then send an advanced tip or offer help. Give a returning customer a relevant next step.
- Test behavior-based branching and a missing event.
- Review a workflow change with both a marketer and an agent.
- Compare audience growth against your actual monthly sending volume.
Contact count changes the comparison
Loops prices paid plans by subscribed contacts and includes unlimited sending. Its published tiers include $49 per month for 1,001–5,000 contacts and $249 for 25,001–50,000. SendOps does not meter contacts, while AWS delivery remains a usage cost. Compare both models at your real audience and send volume.
Both products take lifecycle email seriously
Loops presents marketing, product, and transactional email in one platform and supports lifecycle workflows and agent-based operation. The distinction is not whether either product can automate a welcome series. It is how your team wants to author, operate, and pay for those journeys.
Give agents a workflow definition to work with
SendFlow expresses the whole journey as structured text. An agent can inspect the trigger, adjust a wait, or propose a branch, and your team can review the diff. Keep a copy in your repository while SendOps provides editable, versioned definitions and a visual view for the rest of the team.
Choose the delivery responsibility you want
Connecting AWS adds a setup step: domains, authentication, and production sending need to be ready. In return, SendOps sends through the SES account you own and uses the same foundation as your existing transactional emails. Loops is worth considering when avoiding AWS administration is the priority.
Compare the complete email operation
In SendOps, workflows sit alongside message search, engagement and delivery reporting, suppression management, DMARC monitoring, alerts, broadcasts, templates, and inbound integrations. Include the tools your team would otherwise operate separately when assessing the fit.
Common questions
Does Loops charge per email?
Loops’ published paid plans charge by subscribed-contact tier and include unlimited sending. Its free plan has a combined send limit. SendOps charges a flat platform fee, with AWS delivery usage billed separately.
Does Loops support AI agents?
Yes. Loops promotes agent tooling. SendOps’ agent story centers on readable SendFlow definitions, version control, MCP, and traceable workflow behavior; agent access alone is not unique.
Which is better if I already use SES?
SendOps is designed to connect to your existing SES account and add email workflows and operational tools. If you prefer a fully managed delivery product, evaluate Loops as well.
