The inbox-first operating system for independent publishers

Wrenfield takes the tedious admin off your desk — fast drafting, visual automations and reader records you can actually read.

Start 14-day trial

Clear. Quick. Compounding.

Run your publishing business on your own terms. Gather readers, learn who they are, automate the busywork and sell direct — all in one place. Open integrations and plain-language tools keep the operations quiet so the writing stays loud.

Start 14-day trial

Gather

Meet new readers, collect addresses and keep the opens coming.

Know

Understand who is reading and build something that outlasts a feed.

Automate

Set the repeat work running once and let it keep earning its keep.

Earn

Add income streams without adding another platform to babysit.

The quiet engine behind your list.

Bring in readers who actually want what you write. Meet new people, capture addresses and keep them engaged with letters and landing pages you can build between two coffees. Wrenfield helps you gather a room, not a crowd.

See the page builder

Publish a home base in an afternoon.

Give readers one address for everything you make. Start from a Publisher Profile template and you have a working site before the kettle boils — no hosting bill, no contractor.

Let neighbouring writers grow your list.

What if the people writing beside you were your best distribution instead of your competition? With Swaps you appear inside their sign-up flows, and their readers become yours too.

Sort your readers. Send the right thing.

Group people by what they open, click and buy, so every letter feels addressed rather than broadcast. Better fit, fewer unsubscribes, more replies worth reading.

Through swaps alone I've added a few thousand readers. It's good to see how many people write next door to what I do — and that I can send the favour back.

Know your readers. Keep them close.

Wrenfield lets you tag, group and speak to people individually — so readers keep opening, replying and buying. No shifting algorithm, no scramble for reach. Just consistency, and control over who hears what and when.

See the reader tools

One list, many shapes.

Tag people by what interests them and how they behave, then write letters that sound like a conversation rather than an announcement.

Personal beats polished.

Swap in a first name, tailor a paragraph to a reader's interests, and trigger the next letter from what they did last — all in a couple of clicks.

Land in the inbox, every time.

A letter nobody receives is a letter nobody reads. We tune authentication, warm your sending domain and watch delivery rates on your behalf.

Hand the repeat work to automations.

Publishers who last lean on automations, because they return the most for the least fuss. They are how a one-person shop keeps growing without growing a team — everything ticking along in the background while you think and write.

See the flow builder

Map the journey once.

Automations can be clever without being intimidating. Drag out the path you want a reader to take, and the builder keeps the wiring honest.

React the moment a reader acts.

When somebody buys a guide, clicks a link or fills in a form, send them onward to the thing that fits — while they are still paying attention.

Plugs into the rest of your desk.

Wrenfield connects to the tools you already pay for, like Loomsite and Pledgebox, so your shop, your site and your letters finally agree with one another.

What I like most is that it keeps sending while I'm in the studio with paint on my hands, and I never have to think about it.

Turn letters into income and readers into buyers.

With Wrenfield you can open a shop, run memberships and sell sponsorships without wiring four services together. Several income streams, one place to watch them — which takes most of the dread out of selling.

See the selling tools

Open a shop in ten minutes.

Fees are 0.4% plus card costs, so more of every sale stays with you. List a product, take the payment, and delivery to the buyer happens on its own.

Recommend peers. Get paid.

Point your readers at publishers you actually admire. When somebody subscribes on your recommendation you earn 90¢ to $4.20 each time.

Earn from sponsorships.

Take placements from our sponsor desk or bring your own. You approve every brand and every slot, so the ads read like part of the letter.
