_bhlid?beehiiv's click-tracking token, appended to every link in newsletters the platform sends, tying the click back to the specific subscriber and send.
beehiiv is the newsletter platform behind a large and fast-growing share of the independent newsletters in your inbox. With click tracking on, every link in every email it sends carries _bhlid, an encoded token identifying the click: which send, and which subscriber.
Like Mailchimp's mc_eid and HubSpot's _hsenc, that makes it more than an anonymous campaign label. A link you forward or paste with the token attached still points back at your subscriber record, and the destination site's analytics can log it alongside everything else in the URL.
Yes. The page loads identically without it; only the sender's click statistics lose the event. Given that it identifies you personally as the clicker, stripping it before sharing a newsletter link anywhere is an easy win.
Rather's Link Shortener strips _bhlid and hundreds of parameters like it, right in the address bar and in everything you copy or share. Free, open source, no account, no data collection, and the page you are on never breaks: the cleanup happens after the site has already loaded.
