Adding email address

If you're receiving an "invalid address" error message when trying to send an email from an existing email address to a new email address, there are a few things you can try:

1. Double-check the email address: Make sure you've entered the new email address correctly, with no typos or other errors. Check for misspellings, missing letters, or incorrect domain names.
2. Check for special characters: Some email providers may not allow certain special characters in email addresses. Make sure the new email address doesn't contain any characters that might cause issues, such as spaces or special symbols.
3. Check if the email address is valid: The email address may be invalid or no longer in use. Double-check with the recipient that the email address is correct and active.
4. Check if there is a block: Some email providers may block certain email addresses or domains. Check if your email provider is blocking the email address or domain you're trying to send to.
5. Contact your email provider: If you've tried all of the above and still can't send the email, contact your email provider for assistance. They may be able to help you troubleshoot the issue or provide further guidance.
