Everything the send button never told you
Six things unlimited read receipts add to Gmail, and nothing your recipient will ever notice.
Open status in your Sent folder
No second dashboard to check. Each thread carries its own chip: opened, opened four times, or still unread.
A complete activity feed
Every open, in order, with the time it happened. Repeat opens tell you who is still deciding.
Legal proof of receipt
Export a timestamped technical record of the send and every open it received — evidence you can attach to a contract, an invoice or a formal notice.
Device and location detail
Each open carries the device type and the rough location it came from, so you can tell a forward from a re-read.
Unlimited sends
No monthly credit that runs out on the twentieth. Track every email you send, on every plan.
Invisible to recipients
No footer, no branding, no rewritten links. Your email arrives exactly as you wrote it.
Three steps, and then you forget it is there
Bulk Mail runs inside the Gmail tab you already keep open. There is nothing to migrate and no new inbox to learn.
Add the extension, sign in with Google
One click from the Chrome Web Store. Bulk Mail attaches to the Gmail tab you already have open — there is nothing to configure and no server to point it at.
Takes about twenty seconds.
Write and send exactly as you do today
Tracking is on by default and can be switched off per email. Nothing is added to the message your recipient sees: no banner, no footer, no tracked links.
Works with threads, replies and attachments.
Watch the opens land
Status chips appear next to every sent thread as the opens come in. Open the activity feed for the full history of who read what and when, and export any of it as proof of receipt.
Free shows the last 48 hours. Pro keeps everything.
“We stopped guessing. My team follows up within the hour, and our close rate went up 20% in 60 days.”
Two plans. No seats, no send limits.
Every new account starts with 30 days of Pro. Cancel any time — your tracking keeps working on the free plan.

Writing on outreach, follow-up and proof
Guides to email tracking, follow-up timing and proof of receipt — what the data is worth, and where it misleads.
How email open tracking changes your outreach strategy
Open tracking is not a vanity metric. It tells you when to follow up, which subject lines earn attention, and when a deal has quietly moved to someone else. Here is how to run outreach on open data instead of guesswork.

Questions, answered
Yes. Bulk Mail is the company, and the product is a single Chrome extension listed on the Chrome Web Store as "Email Open Tracker – Unlimited Real-Time Gmail Read Receipts & Tracking". There is nothing else to install and nothing else to buy.
Bulk Mail adds an invisible 1×1 pixel to the emails you choose to track. When your recipient loads the message, the pixel is requested and the open is recorded — the time, and roughly where and on what kind of device it happened. The status then appears next to that thread in your Sent folder.
There is no banner, no footer and no "sent via" link. The pixel is invisible, and nothing about your message changes. You can also turn tracking off per email before you hit send.
Unlimited tracked sends and open status on every thread, forever. The free plan shows a rolling 48-hour window of open history; Pro keeps the complete history, the full activity feed and proof-of-receipt exports.
No. Bulk Mail lives inside Gmail. You compose and send the way you always have, and the status chips appear in your Sent folder on their own.
It is a timestamped technical record: the email, when it was sent, and every open it received, exported as a one-page PDF you can file or attach. When a contract, invoice or formal notice is disputed, it is the difference between saying it was read and showing it.
Open events belong to your account and nobody else. Free accounts keep 30 days of history server-side, and you can wipe everything we hold about your sends at any time.
