The original “Dracula” by Bram Stoker was an epistolary novel: it consists of journal entries (the majority of the work), fictional newspaper articles, and other writings, each dated to a particular date from May 3 to November 6. (There are some large gaps where nothing of note is recorded, and also some days in which entire weeks happen.)
Dracula Daily is an email newsletter that publishes the entire novel (since it's now in the public domain) as one email per day, each email containing that day's entries. (If there's no entry on a day, then there's no email that day, either.) So some aspects are told in chronological order that weren't originally (in particular, the ship's log from the Demeter is only revealed after the ship arrives in port in the novel, whereas Dracula Daily subscribers follow events on the ship as they happen), and the story is told in more of a slow drip-feed over the months rather than being something you binge all at once.
(Though, of course, if you want to read the original novel, nobody will stop you.)
If you want to get the daily emails, you can subscribe to Dracula Daily on Substack.
Or, a fun way to read it is to buy the book, which collects all of the entries in chronological order (including the resequencing of the Demeter log entries) and includes selections of quips, commentary, and fan-art that Tumblr users posted on the #Dracula Daily tag in the newsletter's first year.
