Extension 0.1.6: Hostinger Mail and Mail Orange

• Hostinger Mail. Tracking now works on mail.hostinger.com. The Tracking ON and Clicks ON switches sit just above the Send button in the compose window. They are separate from Hostinger's own tracking option and leave it untouched.
• Mail Orange. Tracking now works in the Orange webmail, for emails written in rich text. A plain text email cannot carry the invisible pixel, so switch the editor to rich text to track it.
• Your own re-reads are filtered out on both, as on the other webmails.
• The switches bar in the compose window now carries the mailcheck logo, so you can tell our switches from your webmail's at a glance.
• On the free plan, each of them counts as one mail client: tracking works in the first mail client you use each month.

A new home page, in 20 languages

The home page has been rebuilt from scratch: what happens after you hit Send, day by day, the four things the extension does, Checky (still in beta), the MCP connector for Claude and ChatGPT, and the six webmails it works in.

Extension 0.1.5: Outlook and SFR in beta, every Zoho region

• Outlook on the web, in beta. Tracking now works for personal accounts on outlook.live.com (Outlook.com, Hotmail, Live). Work and school accounts on outlook.office.com are not covered yet.
• SFR webmail, in beta. The same tracking switch in the compose window, and your own re-reads are filtered out there too.
• Every Zoho region. Zoho Mail accounts in Canada (including zohocloud.ca), the UK, Australia, Japan, China, Saudi Arabia, Singapore, the UAE and Indonesia are now covered, on top of the US, Europe and India. Until now only the last three were.
• Clicks ON, email by email. The click tracking switch now sits in the compose window, next to Tracking ON. Your dashboard setting becomes its default.
• The mailcheck switches now sit together in their own bar in the compose window.

Extension 0.1.1

• Click tracking arrives, turned on from the dashboard.
• Tracking addresses move to getmailcheck.com.

Click tracking, opt in

Open tracking tells you an email was read. Click tracking tells you what the reader went to look at, which is a much stronger signal: someone who opened your proposal and then clicked through to your pricing page is not at the same stage as someone who only opened it.

It is off by default and you turn it on yourself while composing the email, next to the normal tracking toggle. When it is on, the links in the emails you choose to track are rewritten so we can count the clicks, and the recipient is redirected to the original address straight away.

• Free plan: the number of clicks per email. Every click is counted from the day you turn it on, and the full detail unlocks retroactively if you upgrade later.
• Paid plans: which link, when, and how many times.

Two things it deliberately does not do. It never rewrites a link in an email you did not choose to track, and it ignores clicks that come from your own address or from the security scanners that check links before delivery, so the count stays honest.

A contact form

The help page now carries a real form, in every language. Writing to us no longer depends on your computer having a mail client set up, which was a problem for anyone working entirely in Gmail or Zoho Mail in the browser.

Checky, the follow-up assistant, in closed beta

Checky reads your tracked emails and tells you what to do in the morning, then writes the follow-up for you. It is available by invitation during the beta.

• Follow-ups drafted from the original email and the recipient's behaviour, ready to review and send.
• A morning digest of what deserves an action, and nothing at all when there is nothing to do.
• Hot prospect alerts when someone opens the same email several times in a short window.
• Reply detection, so you never follow up someone who already answered.
• A weekly recap: follow-ups sent, replies won, value recovered.
• Address checks included, so the assistant never has you chasing an address that does not exist.

Checky reads the content of an email only when you turn its switch on, per email, and that switch is off by default. See the extension privacy policy.

Bulk verification moves to its own page

List cleaning now lives on its own page with the volume plans unchanged. On the main pricing page, address verification becomes what it always was in practice: a safeguard included with tracking, not a separate product.

Extension 0.1.0

• The extension now gets the addresses of the site and the tracking pixel from the API, so a change of domain no longer requires a store update.
• Both domains are supported at once during the transition. Your own re-reads are still filtered out on either one.
• The Checky switch appears next to the tracking switch, for accounts that have access.
• The toolbar badge turns amber when follow-ups are waiting, green when it is only new opens.

Before that

The extension already did, and still does:

• Open tracking on Gmail and Zoho Mail, switchable email by email.
• Real-time notifications the moment a message is opened.
• Several sending addresses on one account.
• Full history, per-email open counts and CSV export.
• Your own re-reads filtered out, so your statistics reflect the recipient and not you.
• An MCP connector, so you can ask Claude who has not opened your emails.
