How it works
Turn a messy inbox into client workspaces.
MailMate connects to your email account, lets you create client profiles, and pulls together recent conversations and files for each customer. You can keep notes, add contacts, generate quotes, and use AI to summarize what matters.
Group by client
Add one or more contact addresses so related emails and attachments live under the right customer.
Follow up with context
See the latest request, open saved files, create a quote, and draft a reply without hunting through folders.
What MailMate handles
The pieces solo sellers keep juggling manually.
Customer timeline
See each client’s recent emails, sent replies, contact addresses, and working notes in one place.
Attachment library
Save incoming attachments into the customer folder automatically, then open them from the profile.
Quotes and proforma invoices
Create clean PDF quotations and PI documents from the customer workspace.
AI summaries when you choose to use them
Generate customer briefs, work reports, and draft replies. MailMate is local-first; AI features only send selected text to the AI provider you configure.
Privacy position
Your client archive should not become someone else’s dataset.
MailMate stores customer data on your device by default. Email credentials are stored locally using operating-system encryption where available. If you use third-party AI features, only the text needed for that request is sent to the provider you configure.
