I must send a series of important private emails and am setting up a new account for the purpose. But I am concerned that the use of private email providers will increase the likelihood of Gmail/Outlook marking my email as spam. Is this true?
What is your experience with private email providers and having your messages marked as spam? Have you experienced it or not, and with what provider?
If the email is marked as spam is it possible for the sender to know about this? The only solution I can find is the use of “read receipts” but I have never received an email asking for one of these before, and I would not know about these if I was not in this situation. I can imagine myself in the past receiving a read receipt for the first time, suspecting it is a spam because I did not know read receipts were such a thing, and sending to the spam folder. Alternatively, if I did not want to respond to the email, I would not want to tell the sender that I read it.
Also, I know it is sometimes possible for a receiving server to reject the mail entirely, meaning it does not arrive in the recipients spam folder. If this happens, will I be notified?
Lastly, is there anything I should and should not do when sending these emails? I know it is important to refer to the recipient by name, avoid links and unconventional text patterns. Does it matter if I send my email while using Tor or VPN? Does it matter if I use an email client?
Does it matter if I use Proton or its competitors? Should I use the companies domain, instead of a custom domain? It is important that I keep the email account for as long as possible, so I plan on using a custom domain with a cheap provider, unless I am advised otherwise?
Is there anything else I should know?
