In the UK it's exacerbated by our narrow roads, constant drizzle, disrepair of our streets and highways and by the fact that it gets dark by 4PM.

I like the idea of a "Progressively Enhanced Monolith". Start by building the core of the application in something like Laravel that can do anything and be developed quickly, then stick it behind a proxy/CDN like Cloudflare. Then if you find endpoints or pages that are accessed frequently and would be better as their own microservice then use a small serverless worker to either respond directly from the edge or forward the request onto a microservice.
Most places and projects I've worked in the past 10 years or so have used GSuite or similar for inboxes, and Amazon SES or similar for programatically sending email. Those that didn't (shared-hosted websites on CPanel installations seemingly do still exist in 2018) had access to webmail in the hosting panel or as an installable application.
