Manage Lettr campaigns and audience contacts from WhatsApp

Flann connects Lettr to the WhatsApp chat you already run your business from. You ask, and Flann picks the right Lettr action.

Ask about an email, dictate a reply or have Flann prepare a forward, all from the WhatsApp chat you already use with customers. Over time, jobs you trust can run on their own.

60 actions in Lettr. 25 only look things up, and 35 create, update, send or delete. You connect with your API key.

The Lettr jobs you can stop doing yourself

You stay in charge of what goes out. Flann does the reading, the drafting and the chasing.

The same question, answered well

Today

Many of your emails ask the same things: prices, availability, delivery areas, opening times. You type a slightly different answer every time in Lettr.

With Flann

“Reply to the new enquiries in Lettr using our price list and delivery areas.”

Same facts, every time.

What you stop doing: You no longer retype the price list into an email every day.

Bills from the inbox into the books

Today

Supplier invoices land in Lettr as attachments, and someone has to download each one and upload it to the accounting app. It is dull, so it waits.

With Flann

“Move this week’s supplier invoices from Lettr into our accounting app.”

Picking out the emails in Lettr that carry invoices, Flann reads the supplier, amount and due date from each attachment. It prepares a draft bill in your connected accounting app with the file attached.

What you stop doing: Nobody downloads and uploads invoice PDFs by hand any more.
