Dearmailo turns a contact list into separate, personalized messages and sends each one through your own Apple Mail account. Your contacts, drafts, and history stay on your Mac.
Personal at scale.
Local by design.
01 / A clear workflow
Compose a real email with formatting, a subject, your signature, and variables such as first name or company.
Preview the finished message for each recipient and send an optional test email before the campaign begins.
Dearmailo creates and sends separate messages through the sender addresses already available in Apple Mail.
02 / Made to feel familiar
Compose and format the message in one focused workspace. Variables stay visible until each recipient’s preview is created.

Import Excel, CSV, TSV, or TXT files and keep reusable lists on your Mac.

Move between recipients and inspect the exact subject, message, sender, and signature before sending.
03 / Built around your Mac
Campaigns, contacts, signatures, and attachments are stored locally on your Mac. Dearmailo has no delivery server, does not track opens, and does not upload your mailing list.
