The same tool, a different brief depending on your business
Mailwell does not distinguish between industries in pricing or settings – the difference is in what you pull from the platform, and how you put together lists, tags and sequences for your own case. An online shop runs a different cycle than a SaaS app or a monthly newsletter, but the underlying model of subscribers, lists and events stays the same across all four situations described below.
The common thread is the /api/v1/events API endpoint, through which you send Mailwell anything happening in your own system – a completed order, a sign-up, a trial ending, a loyalty milestone. That event then triggers a specific sequence or adds a contact to a segment, so a reaction to customer behaviour does not depend on someone on your team remembering to send it manually.
For agencies and companies with separate clients or brands, there is an added layer of separation at the organisation level – its own database, its own sending domain, its own team. Below are four concrete situations, with the parts of Mailwell each one leans on most and why, so you can picture how it would look in your own case.
Online shops
The sale does not end at checkout. Keep the customers you already won.
- A welcome series for new subscribers after a first order
- Segmentation on order history through custom fields
- Events from your shop trigger sequences
- Campaigns scheduled around a season or a sale
SaaS products
Onboarding that gets a user to first value – and keeps them there.
- An onboarding sequence triggered by sign-up through the API
- Re-engagement when a user goes quiet
- Custom events from your app as triggers
- Webhooks back into your system on opens and clicks
Agencies
Several clients, separated data, one tool.
- A separate organisation per client
- A dedicated sending domain per client
- Unlimited team members on the higher plans
- Reports you can hand straight to the client
Newsletters and media
Regular writing for an audience that asked for it.
- Double opt-in and a clean list from day one
- Sign-up forms you can embed in your site
- A web archive of past issues
- Analytics that show which topics land
Frequently asked questions about use cases
Can Mailwell connect to my online shop, for cart abandonment for example?
Not through a ready-made connector to a specific platform – Mailwell does not ship those. Instead, you send an event like cart_abandoned to the /api/v1/events API endpoint from your own shop or a small script, and that triggers the matching sequence. It works with any platform that can call a REST API.
Is Mailwell a good fit for a small newsletter with a few hundred subscribers?
Yes – the free plan covers up to 100 subscribers and 150 emails a month, which is often enough to start with a single regular issue. The double opt-in sign-up form and the web archive of past issues are available from the lowest plan, so you can build a clean list from your very first reader without needing to upgrade first.
How do I handle several clients under one account as an agency?
In Mailwell, you create a separate organisation for each client, with its own subscriber database and its own sending domain, so client data never gets mixed together. On the Growth plan and above, you add an unlimited number of people to the team, so more than one colleague can work on a client project at once.
Can I connect sign-up in my app to an automatic onboarding email?
Yes – a sign-up in your app calls the API and enrolls the new user in an onboarding sequence, or sends a custom event that the sequence reacts to. Automation sequences are part of the Growth plan and above; calling the API from your own app needs the Pro or Enterprise plan.
How does Mailwell keep one client's data separate from another's when I manage several brands?
Every organisation in Mailwell has its own, separate database of subscribers, lists and campaigns, even when you manage several from a single account – one brand's data never shows up in another's interface or exports. On top of that, each organisation gets its own sending domain, so brands do not share sender reputation with each other.
