Why the fuck should I pay for SSL and email after buying a domain?

For people who don't know letsencrypt exists

@alexbrooklyn Or for people who want to use another CA.
Or an extended validation cert. Or many other reasons.

SSL: up to you. Not all types of certs are free and for a reason.
Email: you're saying you can host/manage an email server for free?

TLS.

SSL is dead. Deeeeaaaaddddd.

And the reason why...

Dude. Take a look at the news.

It's currently not exactly sunshine and "it's raining men" from the weather girls feeling out there.

Sooner or later, TLS will be mandatory by certain APIs / Providers / ISPs .

Simply because the world is a fucked up place - and without TLS noone would want to offer a contract for a domain in a world wide web.

I don't know... maybe because they are different services?

I don't know who sold you a domain and made you think you should get an email and a SSL cert with that. Whoever it is, is a good seller

@JhonDoe this sounds like a GoDaddy endeavour.

Because you feel it should be included in the price? Or because you really don't know why you should buy SSL?

You don't need to buy one IF you think you don't need it

Though irrelevant, you can't "buy" a domain, you can rent it.
