How it works
Explain in

Email has become everyone's second job. About two hours a day go to the inbox, and most of them to the same tasks, again and again. Chase a follow-up. Confirm a delivery. Check an invoice. And somewhere in between sits the one mail that could cost you a deal.

  • The quote nobody chased

    It went out, nobody followed up, and the customer bought somewhere else.

  • The approval that waited

    One yes sat in an inbox, and the whole order waited with it.

  • The one who knows is away

    Their customers wait until they are back, and nobody else knows the history.

Today's AI makes that work faster. We think it should make that work disappear.

MailNail does the work that arrives by email.

It knows what each mail is about, does the repeated part, and brings you only what needs you.

Your company brain, in every reply.

Price lists, contracts, delivery terms. MailNail knows what your company knows, and writes each reply from it.

  • Files, sheets and documentsKeep them in MailNail, or write them there. The attachments in your mail are already in.
  • Every figure shows its sourceA price, a date or a discount in a draft points to the line it came from. You check it in one look.
  • No source, no numberWhen your files do not hold the answer, MailNail asks you. It does not guess a price.

Everything it does.

One product for the mail, the work in it and the files behind it.

  • Automatic follow-ups

    A mail that got no answer has its follow-up written on the right day.

  • Replies in your voice

    The mail that needs you comes with a draft, written the way you write.

  • Dockets

    One place for each customer, deal and order, with its mail, files and dates.

  • Tags that set themselves

    Every mail is sorted by what it is: a quote, an invoice, a delivery.

  • Dates and to-dos

    A deadline in a mail becomes a to-do or a calendar entry, with a reminder.

  • Workflows

    Set the steps once. MailNail runs them for every mail of that kind.

You stay in control.

What every team asks us before a pilot.

Will it send something wrong?

Nothing goes out until a person approves it.

Later, your team can choose what may go out on its own. Every step stays on record.

Is our mail safe with you?

Your mail stays your company's. We use it only to do your team's work, under a data processing agreement.

It never feeds ads or trains AI models, and you can delete it at any time.

Does it work with our provider?

Yes. Gmail, Microsoft 365 or any other mailbox, and your addresses stay the same.

We can also host them on your own domain.

How much setup does it take?

Very little. Connect your team's mailboxes, and MailNail starts on its work from the first day.

Your team can change anything it does.

Can we use our own AI?

If you like. MailNail can run on your own OpenAI, Anthropic or Google key, and your provider bills the usage.

Your own AI assistant can work with your mail too, within the access you grant it.

Join the pilots

Paid pilots are open now, for teams whose business runs on email.

Explain in

MailNail is AI that runs your company's email. It does the repeated work that arrives by mail, and a person approves what goes out.

A writing assistant helps one person write one reply faster. MailNail knows which customer, deal or order each mail belongs to, and does the follow-ups, confirmations and reminders itself.

Not necessarily. MailNail keeps track of every customer, deal and order from your mail, so a team without a CRM does not need one. A team that has one keeps it, and MailNail can keep it up to date.

Yes. Keep your files, sheets and documents in MailNail, and each draft takes its facts from them. Every figure in a draft shows the line it came from. When your files do not hold the answer, MailNail asks you.

MailNail is built to give every person back about 20 hours a month. Every pilot counts the hours from the first week.

Sign up with your work email, and we send your invite. Your team connects its mailboxes, and MailNail starts on the repeated work. Every pilot counts the hours it gives back. If it does not give your team time back, we stop.

MailNail opens to everyone in early 2027. Paid pilots are open now, and your team can start today.

The two hours a day come from McKinsey Global Institute, The social economy, 2012: email takes 28% of the workweek, about 2.2 hours of an 8-hour day. MailNail takes over the repeated part of those hours, which comes to about 20 hours a month per person.
