Email Tool Unable to Send Email

Hi All,


I am trying to send an email using the email tool within Atleryx from my corporate email account. However, I run into the following error:


Email (1) Record#1: Unable to send email: "Error with Message: 421-4.7.0 [IP redacted] Our system has detected that this message is ¶421-4.7.0 suspicious due to the very low reputation of the sending IP address. ¶421-4.7.0 To protect our users from spam, mail sent from your IP address has ¶421-4.7.0 been temporarily rate limited. Please visit ¶421 4.7.0 for more information. j73si5186071ywb.416 - gsmtp ¶"


I have tried to follow the link provided but didn't see any way to incorporate that into Alteryx. Does anyone have any experience in solving this problem?

Hi @MichaelF1 


Looks more like an e-mail problem rather than an Alteryx problem.


I've seem some people commenting that this might be due to some blocking Google does.
