Error sending emails

Error sending emails


I'm extracting email addresses from a database and using the RichMail extension to send emails. If there are several recipients it works fine (To:;;;) but if there is just the one address I get the following error:

Email creation error: 501 5.5.4 Invalid Address
RCPT TO: <>;

Is this a known issue and is there a workaround of some sort? This only happens if the email address is extracted from the database; if I enter the address directly into the To property of the RichMailCreate action in Service Studio it works fine.

If there is a single address you should not add the last semicolon. Intead of
Try to send it like
Let me know if this has fixed your issue.
