How do I send a single transactional email via Acumbamail?

Short answer: You can send transactional email in Acumbamail by hand from its own interface, but it won’t repeat itself. On TinyCommand, add the Acumbamail Send Transactional Email action to a workflow, map its 5 inputs from any upstream app, and it runs automatically every time the trigger fires. No code, and a free tier to start.

FAQ

Questions about Send Transactional Email.

What does the Send Transactional Email action do in Acumbamail?
Sends a one-shot transactional email to a single recipient with subject, HTML body, and optional attachments. For sender-reputation hygiene, use separate Acumbamail sub-accounts/keys for transactional and marketing — mixing degrades deliverability over time.
What inputs does Send Transactional Email require?
Required: From Email, To Email, Subject, HTML Body. Every input accepts a static value or a variable from any upstream node in your workflow.
Can I use dynamic inputs from earlier workflow nodes?
Yes. Any field on this action can pull values from upstream nodes, whether that's a form response, a trigger payload, an AI output, or a lookup result.
What happens if Acumbamail returns an error?
The workflow pauses on the failed node, the error message is captured in the run log, and you can retry the run with one click. Auto-retry policies are configurable per workflow with exponential backoff up to 5 attempts.
Does Send Transactional Email support batch operations?
Yes. Run Send Transactional Email inside a Loop node to process arrays. TinyCommand handles Acumbamail's rate limits automatically so you don't have to throttle manually.
