## About Sendy

Sendy is a transactional email service for applications. It sends password resets, receipts and notifications from a domain you verify, through an HTTP API or SMTP. Managed queuing and automatic retries handle temporary sending failures, and delivery feedback shows sending attempts, reports and bounces.

Setup starts with verifying a domain you control. The dashboard guides you through the DNS records for DKIM, SPF and DMARC, then you create an API key and submit emails as JSON. Idempotency keys help prevent duplicate messages when your app retries a request.

Credits are bought as one-off top-ups from Ksh 50 at Ksh 50 per 1,000 emails, with no subscription and no expiry on purchased credits. Each account gets 50 test emails once after DNS verification. Online M-Pesa checkout is coming soon, so top-ups are arranged through support for now.

## About Senlo

Senlo is a layer on top of the email delivery provider a team already uses, such as Resend, Postmark or any SMTP server. It gives you a visual editor for transactional email templates, with rows, columns, merge tags and conditions, and versions you can roll back to. Templates can be sent through a single API request, and developers receive the same template through the API without writing MJML by hand.

Lifecycle automations start from events sent to the API, such as a new contact being added. An automation can send an email, wait, check your own API whether a user did something, and then take a different path. Each node shows how many contacts are in it. Sends, deliveries, bounces and engagement are shown per workspace, with a live feed of failures and a suppression list. Senlo renders, personalises, tracks and decides, then hands each message to the provider you chose, so switching providers does not require editing templates.

The product suits teams that send transactional email and onboarding sequences and want editors who do not write code to work on them. It can be self-hosted with Docker Compose under the AGPL-3.0 license, or used as a hosted service with a free plan for one person, and paid plans that add members, roles and audit logs.
