Defaulting to email provider page

Question

Even though I've added all my email accounts, my iPad often defaults to the email provider page. The only way I've found to get back to email is to add an existing account then subsequently deleting it.
I also then get messages from 'no sender' dated Jan 1970 which Icannot delete but often vanish of their own accord.

Answer 1

My email accounts were set up and operated perfectly until reecently. When I now access the mail app often the page opens with the list of email providers . I cannot get past this to open my email accounts. I have on occasion closed an email account and re-entered it; I've also gone to settings and closed all email accounts and then opened them. Sometimes these actions work but at present nothing works and I cannot receive or send emails.
Any help will be appreciated.
