Question 1

How is my security and privacy protected?

Accepted Answer

The app only has email-send permission while you're using it - it cannot read your inbox or perform other actions. The auth token expires every 1-2 hours, and credentials are stored only in your browser. Since everything happens locally, your data (contacts, emails and send history) will never be sent to any external server.

Question 2

Will my bulk emails be marked as spam?

Accepted Answer

Emails are sent from your own Gmail account, so they're treated like regular personal emails. A few hundred to a few thousand emails are usually fine, but sending identical content repeatedly may trigger spam filters. To reduce the risk, send in smaller batches and personalize your emails with template variables.

Question 3

How many emails can I send at once?

Accepted Answer

Send Bulk Email itself has no limits, but Gmail allows up to 500 emails per day. If you need to send more, spread them across multiple days.

Question 4

How does this compare to MailChimp?

Accepted Answer

MailChimp and similar services offer better deliverability through dedicated sending infrastructure. Send Bulk Email is best for simple, quick campaigns - no signup, no fees, no learning curve.

Question 5

Why is it free?

Accepted Answer

I originally built this for myself. I needed to send cold emails for my own app, but services like MailChimp felt overkill and expensive for what I needed. I'm happy to share it with anyone who has the same problem.

Question 6

Can I schedule emails?

Accepted Answer

Not yet, but scheduled sending is coming soon!

Question 7

Can I create HTML or visually rich emails?

Accepted Answer

Right now you can use text formatting (headings, subheadings) and attach images and files. Full HTML email editing is on the way — coming in an upcoming release!

Question 8

Can I use this for newsletters?

Accepted Answer

Yes! Send Bulk Email works great for newsletters. Import your subscriber list, compose your newsletter with the rich-text editor, personalize with template variables, and send — all for free through your Gmail account.
