You can’t, because normies don’t care about tech other than it benefits them directly in some way. They care about the experience they get and doing the same thing everyone does because normies are like sheeps.
Normies barely even get how emails work and it’s been like over 40 years. They know if they sign up for Gmail it’s free, they get a ton of space and an @gmail.com address. That’s it.
And even then, people looked at me weird back in 2007 when I made my Gmail account because “everyone uses Hotmail, why wouldn’t you use Hotmail, everyone uses it so it must be the best”. Heck just yesterday, the teller at the mechanic shop looked at me weird because I used [email protected] to place the online order, they were utterly confused. They thought I made a Gmail or Outlook for all of those aliases. People don’t think about using emails, they think about using Gmail or Hotmail/Outlook.
Same with Reddit, it didn’t become popular until normies felt like they were missing out by not being on Reddit, and arguably that was Reddit’s downfall flooding the site with the same repeated arguments and opinions over and over. And for that too, I’ve been told my “Reddit looks weird” because I use a third-party app. People want to use Reddit so they download Reddit.
Normies don’t use Twitter because they want to microblog, they use Twitter because their idols are on Twitter and they want to mimic them. If Taylor Swift opened a Mastodon account and posted exclusively there, we’d get a massive spike of users. And they all would want to register on the same instance as her and it would be the only viable instance to them.
They just want to fit in and do the same as the others, using the same services and same apps and everything. “Influencers” are everything these days.
The best way to get normies on the Fediverse is IMO, endorsing Threads and BlueSky, which will effectively force them to integrate because those platforms integrate.
