Bulk Gmail Sender for Windows

TechBotMaster Gmail Sender sends personalised emails to your own list through your own Gmail account, from your Windows PC. It stays inside Gmail's limits, skips addresses that bounce and keeps a record of every run.

What it does

Personalised emails. Use {name} and {city} in the subject and the body, with a fallback such as {name|friend}.
Attachments and an optional CC for each recipient.
Import from Excel or CSV and save contact groups.
Safer sending: a gap between emails, a pause after each batch, an hourly limit, a daily limit and a warm-up mode that starts slowly.
Bounce and STOP protection. Addresses that do not exist are remembered and skipped next time. One button reads your Gmail inbox for bounce notices and replies that say STOP and adds them to a do-not-email list.
An optional unsubscribe line at the end of every email and an unsubscribe header, which lowers spam complaints.
Schedule and repeat campaigns, and see every run in the reports with a CSV download.

How it connects to Gmail

It uses Gmail's SMTP with an App Password, not your normal password. You turn on 2-step verification in your Google account, create an App Password for "Mail" and paste it into the app. The App Password stays on your PC.

Gmail's own limits

A free Gmail account can send roughly 500 emails a day and a Google Workspace account roughly 2,000. Going over, or sending to people who report you as spam, can make Google limit or suspend the account. The app has a daily limit set by us and your own hourly limit to help you stay under, but you remain responsible for who you email.

Good practice

Email people who expect to hear from you.
Keep the unsubscribe line on and remove people who ask.
Start small and grow slowly, especially with a new account.
Do not use a misleading subject line.
