An AI email marketer that writes and sends lifecycle emails

What is Mara?
Mara is an AI email marketer that drafts, sends and tests welcome, nudge and win-back emails for software products. It learns the founder's voice, connects to auth and billing tools, and runs A/B-style iterations after the owner approves each version.
Mara is an AI email marketer built for software products that lack a lifecycle email program. It drafts the messages a product should already be sending: welcomes for new sign-ups, nudges for trials that have gone quiet, and win-backs for customers who left. The founder reads each draft, edits a line if needed, and approves it. Mara then handles sending, testing and follow-up. The tool is aimed at small SaaS teams and solo builders who know they need onboarding and retention email but have no time to write or maintain it. Setup starts by giving Mara a product URL and two or three real emails, from which she learns the founder's greetings, sign-off and how quickly the writing gets to the point. The homepage shows twelve invented companies, each with a different extracted voice, to illustrate how far the style can vary. In practice, Mara connects to the systems a product already runs. Clerk or Supabase tells her about every new sign-up, Stripe or Polar webhooks report upgrades and cancellations, and a small Mara API reports what users do inside the product. Those signals decide who gets a welcome, who gets a nudge and who stays untouched. Teams can also pass a setup prompt to a coding agent that wires the connection over MCP. Two behaviors set it apart from a basic automation sequence. Every send goes out as competing versions: the ones that draw replies receive a larger share of the next batch, weaker ones are rewritten into new challengers, and the owner still approves every version before it enters the test. Emails can also end with a genuine question, with replies reaching both the founder's inbox and Mara, who drafts the response and uses the answers to shape later copy. Among alternatives, Mara sits between general email platforms that expect users to write and schedule everything, and generic AI writing tools that produce copy without sending or measuring it. It suits products that want lifecycle email handled end to end without migrating off their current stack.
How do you use Mara?
1Enter your product URL
Start from the homepage by entering the product URL and choosing to see a first email. Mara drafts a sample based on the product.2Create an account and hire Mara
Sign up and paste two or three real emails you have written. Mara uses them to pick up your greetings, sign-off and pace.3Connect auth and billing
Link Clerk or Supabase for sign-ups and Stripe or Polar for billing events. Each connection takes one click from onboarding or settings.4Send product events through the API
Use the Mara API, or hand the setup prompt to a coding agent over MCP, so she can see what users do in the product.5Review and approve drafts
Read each drafted welcome, nudge or win-back email, tweak a line if needed and approve it before it enters testing.6Watch iterations and replies
Mara sends competing versions, shifts volume toward the ones that get replies, and drafts responses to what people write back.
Pros and cons
Pros
- Drafts welcome, nudge and win-back emails in the founder's own voice from just two or three sample emailsAI
- Owner approves every email and every test version before anything is sentAI
- Connects to Clerk, Supabase, Stripe and Polar plus a small API, so no migration is neededAI
- Competing versions are sent and rewritten automatically, so copy improves without constant attentionAI
- Replies reach both the founder and Mara, who drafts responses and learns from the answersAI
Cons
- Auth integrations are limited to Clerk and Supabase, and billing to Stripe and Polar, per the homepageAI
- Pricing is not stated on the homepage, so cost cannot be judged before signing upAI
- Focused on lifecycle email for software products, so it does not cover newsletters or broader campaignsAI
- Approving every draft and test version keeps a human in the loop, which adds ongoing review workAI
- Proof on the homepage is mostly launch badges and social posts, with no independent case studiesAI
