Where to start in Lovable
Paste this into Lovable as the opening prompt. It sets up one screen and one job, which is easier to grow from.
Build an email marketing tool where a user connects their store via a webhook or CSV of customers, writes one campaign brief in plain language, and the app generates three subject line variants and three body variants split-tested automatically across the list. Show a results screen with open rate and click rate per variant after 24 hours, and let the user pick a winner that auto-sends to the rest of the list.
What you will need to wire up
- Lovable AI Gateway
- Lovable Cloud (Postgres)
- Provedor de envio de email (Resend ou similar)
- Webhooks de loja
- Stripe
Build order
- Get sending infrastructure right before AI. Domain authentication, bounce handling and unsubscribe links are boring but they decide whether any email arrives at all. Get one plain campaign sending reliably before adding generation.
- Generate variants against the brief, not from thin air. Force the campaign brief to include product, offer and audience before the model writes anything. Vague briefs produce generic subject lines that all test the same and waste the split test.
- Split test on a real minimum sample. A list of two hundred cannot support three-way testing with statistical honesty. Cap variant count based on list size and be upfront in the UI when a result is not significant yet.
- Auto-send the winner with a delay and an undo. Give a fifteen-minute window between picking a winner and the send going out to the rest of the list, with a visible cancel button. Automated sends that cannot be stopped are how you lose a customer permanently.
Where this usually breaks
- Deliverability collapses silently when a customer's domain lacks SPF or DKIM records. Check them on connection and block sending with a clear setup guide instead of letting emails land in spam unnoticed.
- Generated subject lines can drift into spammy patterns like excessive punctuation or all caps words, which trips spam filters. Run every generated line through a simple keyword and formatting check before it is allowed into a test.
How it makes money
- Monthly plan tiered by contact list size. Standard in this category, customers already expect it and it scales with the value they get.
- Add-on fee per AI-generated campaign. Lets you monetise heavy AI usage separately from the base sending plan without punishing light users.
