Reply in seconds, even when you're busy

Why 30 minutes can cost you the job.

When someone emails you for a quote, they're probably emailing your competitors too. The first to respond usually wins. But when you're on a job or driving, who has time to check emails?

With Coliflo <10 sec The reply is already drafted when the notification arrives. Read, tap Send — minutes, not hours.

Don't miss the emails that matter

What happens when emails pile up.

The more emails you receive, the more you miss. Quote requests get buried under newsletters, spam, and notifications. By the time you see them, the client has moved on.

With Coliflo 0 noise Newsletters, promos and spam stay in Gmail. If nothing matters, Coliflo says nothing.

Handle email like a chat

You didn't start your business to spend evenings on email. But quotes, invoices, and messages pile up. Every hour on admin is an hour you're not earning — or resting.

Your security, our priority.

Encryption, Swiss hosting, nothing ever sold — security is built into every step.

Google OAuth certified

Coliflo operates using Google's recommended access level: read and send emails, without modifying drafts or deleting messages.

Google Verified

Encrypted, and yours

Subjects, bodies and drafts are stored encrypted with AES-256-GCM, and the keys are held outside the application. They're kept for one reason: so you can pull up the original of any email from WhatsApp, whenever you want.

Never sold, never used to train AI models

What the AI sees, and nothing more

The AI receives the sender, the subject and the text of the email — what it takes to write the reply. Never your Gmail credentials, never an attachment, never anything from the rest of your inbox.

Nothing is retained to train a model
256-bit Encrypted

Only what you ask for

WhatsApp carries a short summary and the draft. The full text of an email is shown only when you tap See original — nothing else leaves your inbox.

Attachments are never transmitted or analyzed

Secure hosting in Switzerland

Our servers are hosted in Geneva by Infomaniak, an ISO 27001-certified provider known for its high security standards.

Frequently Asked Questions

Coliflo is an AI email assistant that lets you read and reply to your Gmail emails directly from WhatsApp. The AI reads the register of the email it answers and drafts a reply in the same key and the same language, and you approve or edit it from a simple WhatsApp conversation.
You connect your Gmail account once — it takes 2 minutes. Your important emails then arrive in WhatsApp: you can read, reply and manage your inbox without opening your mailbox or installing an app.
No installation required. Coliflo works directly with your Gmail and WhatsApp accounts. Simply connect your Gmail once via Google OAuth and you're ready to go.
Coliflo is built for freelancers, tradespeople, real estate agents, consultants and small businesses who want to handle their emails faster, without spending hours in their inbox.
Coliflo has one plan: 11.90 € per month (or 119 € per year — two months free), a launch price locked for life for the first 50 users; the regular price is 24.90 € per month. Everything is unlimited — emails, edits, replies. In US dollars: $13.90 per month or $139 per year. All prices exclude tax. Every account starts with a 7-day free trial, no card needed.
Our AI sorts your inbox based on importance and relevance. Only useful or action-oriented messages are summarized and delivered to WhatsApp. Spam, newsletters, and irrelevant emails stay in Gmail.
Yes. Replies are automatically written in the same language as the sender's email — English, French, German, Spanish, and more.
Coliflo never opens or analyzes attachments, and never sends them to the AI. When a reply depends on what's inside one, it doesn't guess: it skips the draft and tells you the email has to be handled from Gmail.
You see it from the start: the summary carries a (+2 cc) badge when other people are in the loop. And when you tap Send, Coliflo asks whether to reply to the sender only or to everyone — so reply-all is always a choice, never an accident.
Coliflo analyzes the received email along with the last message in the conversation. This helps the AI understand the context and suggest a coherent, natural reply.
Edits are made one email at a time. While a message is being modified, it must be sent or ignored before another one can be changed. This keeps a clear and structured workflow for your replies.
Your emails remain unread in your Gmail inbox, so you stay in full control. You'll simply see the message that Coliflo sent in reply — making it easy to track what's been done.
Yes. Coliflo is Google OAuth certified, encrypts everything it stores — your Gmail access and the emails themselves — with AES-256-GCM, never sells your data and never uses it to train AI models. Developed and hosted in Switzerland by Calidris Sàrl.
