If you are doing a small services startup with only a few pages, I use Amazon’s free tier right now for my running club’s website dch4.org - https://aws.amazon.com/free.
You can host an instance of WordPress, Jekyll or Nodejs on there and hook up Amazon Simple Email Service to your domain.
Boom - free web hosting, transactional email, and email marketing within some limits.
I haven’t tried it, but, Amazon’s workmail looks super cheap and promising.
The pricing is more complex than Google Cloud’s or Heroku’s or surge.sh’s, but, I think it is perfect for starting a small agency, web service, or consulting type business.
Because the cost is real low and you don’t have to go out to a ton of 3rd parties for your email, document hosting, email marketing, payment process etc etc etc.
