Write your inquiry once, tick your companies, press send — each copy goes out from that company's own Gmail with its own details and signature. Built for people who wear more than one hat.

Sign in to each company's Gmail through Google's own consent screen. Send-only permission — Diversimail can never read your mail.
Company details, phone, license number, sign-off — saved once per account, attached automatically to the end of every email it sends.
One message, checkboxes for your companies, one button. Every copy lands from a different sender with its own identity.
Click any email address on any website and the compose window opens with the recipient pre-filled. One less copy-paste while you hunt suppliers.
If one account fails, the successful ones untick themselves — pressing send again retries only what failed. Invalid addresses stay in the field, flagged.
See exactly what each company's email will look like — shared text plus its fixed part — before anything goes out.
Close the popup, reload the browser — your unsent text is still there. The form clears only after every send succeeds.
Diversimail runs entirely in your browser. Messages go straight from Chrome to Gmail; accounts, signatures and tokens are stored locally on your machine. There is no Diversimail server anywhere in the path — nothing to leak, nothing to sell. Read the privacy policy →

Yes. Install it, connect your accounts, and make 5 free sends — each to up to 3 recipients from up to 3 of your accounts. No card, no email. After that it asks you to subscribe.
Our other tool for the same desk: click any phone number on DAT or any page and your Polycom desk phone dials it, hands-free. Same subscription, same email to activate — callbyclick.com.
No. It requests Google's send-only permission (gmail.send). Reading, searching or deleting mail is technically impossible with that permission — and you can verify what was granted anytime at myaccount.google.com/permissions.
No. Each email is a completely normal Gmail message from that account — same as if you'd typed it in Gmail yourself. Replies land in that account's inbox.
Yes — personal Gmail or Google Workspace (custom-domain) accounts both work. Other providers are not yet included.
Yes — Chrome disables extensions in incognito by default, but you can allow Diversimail there in ten seconds: chrome://extensions → Details → "Allow in Incognito."
In your browser's extension storage, on your device. We run no servers and receive nothing. Details in the privacy policy.
