We started to use xfinity and was allowed to use our email user name. Recently, our email has messed up. I can receive email on my iPad but can not send email.

Start with initial fault finding:
What happens when you try to receive or send email? Do you see any errors - and if so, what do you see?
If email is failing to send or receive, you are likely to see indicative errors at the bottom of the mail sidebar - the wording of the error usually providing sufficient information to determine the nature of the problem.
Deleting and re-adding your email account is sometimes the easiest way to resolve a problem with a specific Mail account. After deleting the account, perform a forced restart before re-adding the email account to your iPad.
Settings > Mail > Accounts > [Your Mail Account] > Delete Account
Force restart iPad - Apple Support
Settings > Mail > Add Account
Also be aware that some email providers now require the use of App Specific Passwords when accessing mail over IMAP or POP3. If this applies to your email account, you will need to generate a unique password for your iPad email account - that will differ from your normal Account Password. As examples - AOL, Yahoo, Google, Microsoft all use App Specific Passwords when using anything other than their own email client Apps.
If you need to generate an App Specific Password, you’ll need to log-in to your Mail Providers account management webpage - using a web browser - and generate the Password from the appropriate account security page.
