3. Emails with 4-5 GB per inbox. Let's say each user has 2 inboxes, and there are 10 domains, so you have in all 20 inboxes. Now for that 20, you will need at least 100gb of space. I would suggest you have a look at Zoho, GSuite, Rackspace or other providers for emails, as you will use up all your disk space in the emails!Thank you, these are great questions.
1- I want to collect all website in one location so my guess reseller option good for me( for my client). I dont want to "add-on domain" because i really dont want to mess around with it.
2-Yes i am maintener these websites and i will ( hope)
3- Email is tricky. Just one domain (gTLD one which is domainname.com) i wont migrate MX records to European Company but others ccTLD domains i have no idea. Probably we need email dedicated with that company and it should be at least 4-5 GB per inbox
4- It should be great extra benefits like "Litespeed server", extra speed features , dDOS protection, easy to setap Let's Encrypt, SSD drive. A2 Hosting Bronze plan features seems fit for my client but i could not be 100% sure that company "reliable". As you know that most hosting company just "write features" but they could not provide that.
Thank you for suggestion.3. Emails with 4-5 GB per inbox. Let's say each user has 2 inboxes, and there are 10 domains, so you have in all 20 inboxes.

If you see A2, their singup costs are pretty low, but renewals are quite high. If you go with the monthly plan there is a 30% jump, plus you have to pay extra for LiteSpeed (INR 752). I would suggest, instead buy a VPS which is managed (DirectAdmin is cheaper), and you can then create multiple accounts for your users.Thank you for suggestion.
Dont "let's say" i can say real number. Each domain (not user) will be use just 2 emails. When you calculate total looks like equal but in the long term there have differences (domain number wont change but users can be change etc). For that reason, im looking flexible plan which i can make changes which email box is 4 GB which is 1 GB etc.
By the way i was used Yandex Busines Mail for one client but they did not satisfy.
