This series is the Trope Namer for:
Strong Bad: Um... no, from what I can tell, you wear no pants and have blue soles glued to the bottoms of your feet.
- Keep Circulating the Tapes: The five bonus emails exclusive to the DVDs were only released on said DVDs.
- Milestone Celebration: For every 50 emails, plus the 125th email.
- In #50, "50 emails", Strong Bad attempts to answer 50 emails in one sitting, but he gets side-tracked by a phone call. Then Homestar tries to take over, but causes the Compy to undergo a "flagrant system error".
- In #100, "flashback", Strong Bad relates to the viewers (and Homestar Runner, who happens to be Behind the Black) the story of how he first met Homestar, in "WIDESCREEN!" no less.
- In #125, "rock opera", Strong Bad composes a rock opera with Word Salad Lyrics cribbed from his first 125 SBEmails.
- In #150, "alternate universe", Strong Bad rigs up an alternate universe portal and visits his many alternate selves, including Strong Badman, Old-Timey Strong Bad, and Tiny-Handed Strong Bad from The Homestar Runner Enters the Strongest Man in the World Contest.
- In #200, "email thunder", Strong Bad is all set up to answer his 200th Strong Bad Email, only for the latest e-mail to be addressed to Homestar, who has somehow had his own email show for years.

- Technology Marches On: While this is averted in most aspects due to Strong Bad using computers that were old even at the time (his newest computer has 16-bit graphics at best), starting with "too cool", responses are now pulled from Strong Bad's official Twitter account rather than his email address, reflecting the rise of social media as the internet's primary form of communication in the 2010s.
- Throw It In: The Brothers Chaps didn't realize they skipped over 22 when numbering the emails until after "little animal" was released. They then decided to present "sb_email 22" as a lost episode which was posted in between Strong Bad's last postcard from "vacation" and "invisibility".
- Unintentional Period Piece: The bonus e-mail "comic book movie" was released in 2008 and primarily mocks common comic book movie clichés of the mid-2000s, especially the X-Men Film Series (Movie Superheroes Wear Black, they don't wear masks, poorly-done CGI, and so on). Also in 2008, Iron Man was released, which began the Marvel Cinematic Universe and completely changed the landscape of comic book movies; the series is especially known for its comic-accurate costumes (bright, colorful, masks included and not entirely leather) and focus given to perfecting the visual effects. Even so, while Strong Bad's lampooning of the subject is outdated from a post-MCU point of view, many of his complaints still hold true for its imitators.
