Agradezco apoyo, pues a la hora de añadir un nuevo email de remitente, tengo este error:

Hi JhonattanCabralesLara,

Thanks for reaching out to Jotform Support. Unfortunately, our Spanish Support agents are busy helping other Jotform users at the moment. I'll try to help you in English using Google Translate, but you can reply in whichever language you feel comfortable using. Or, if you'd rather have support in Spanish, let us know and we can have them do that. But, keep in mind that you'd have to wait until they're available again.

Now, let me help you with your question. The error message shown in your screenshot indicates that your SMTP credential is incorrect. Please test out your SMTP credential on this page to double check it. If the issue doesn't persist, please let us know.

Give it a try and let us know how it goes.
