I'm using python lib boto for sending emails via SES. And when I tried to send to more than 30 (but less than 50, so limit is not exceeded) recipients, I got an error:

  <Error>
    <Type>Sender</Type>
    <Code>InvalidParameterValue</Code>
    <Message>Missing final '@domain'</Message>
  </Error>

My to_addresses is empty list, all recipients are in bcc_addresses list.

What does it mean? Every recipient's address is valid and sender address is verified and valid.

    Do you have the setFrom set with a valid and authorized email address? – Abela Jan 01 '15 at 03:00
  • Make sure you check *all* email parameters that get included in the SES/SMTP call - in my case all From, To, CC etc were correct but I had a Reply-To (inserted by some custom logic) which wasn't a valid email - literally "missing final @domain" – Janaka Bandara Nov 04 '21 at 04:27

I had this error and the problem was the my to_addresses email address was malformed.

I used a malformed e-mail address in Source when I got this error.

Recently there might to be an issue with putting an email address at the end of a sentence that ends with a period the content of a message (in text/English) like:

"Send your request to user@domain.com."

SNS or some of message processors (on AWS) now appear to process textural content for words that look like domains. The sentence above passes grammar checks however seems to fails a regex for valid domain the period at the end suggests the could be follow on characters.
