I'm working in a small start-up company. And, as you can imagine, money is scarce!
I currently have 3 email addresses that are provided with my VPS.
For security reasons, I am interested in switching to ProtonMail, but unfortunately, they seem a bit expensive for the plan I want.
Currently they offer a "professional" plan that would allow me to have an encrypted email with my own domain name. The problem is that this costs $ 8 / month and they tell me that I would have to pay for a separate user account if I want my 3 email addresses separated.
I would like to have: email@example.com, firstname.lastname@example.org and email@example.com
So, for that to happen, I would end up paying $ 96 / year for email account for a total of almost $ 300. (That's a lot of money when I do not even know if my company will survive the first year of business).
So this leads to my question …
The ProtonMail support told me that, instead, I can opt for their "Plus" plan, which would consist of an account (ie, Inbox), but would allow up to 5 email addresses with "aliases".
They are telling me that with the "Plus" account, I could use filters to organize all the emails that arrive to the account and divide them into separate folders. And when I asked about responding to customers, they assured me that by replying to the email with alias it would be filled in the "To:" field, I could reply to an email and make it appear to come from cat @ mycompany. com
Is there any reason why you DO NOT want to opt for this more affordable option that uses aliased email addresses?
My biggest fear is that email servers and spam filtering software, and to a lesser extent, "investigative" clients, can look at the headers of emails and determine that all of these different email addresses actually come from from a single email account, and that in turn puts me on a spam list or loses the trust of the clients because it seems that I am plotting something "suspicious".
What do you think of all this and what do you think I should do?
They have a sale until the end of Friday (tomorrow), and I'm interested in being paid with ProtonMail, but I'm not sure which is the best option?
