Do I have to use IMAP protocol to make a bot to reply emails?

You don’t use IMAP nor POP3 to send emails. You use SMTP

@Andoni  why dont I use pop3 or imap?

I use pop3 to send emails, that works. I just couldnt make the bot reply to emails..

I highly doubt it. POP3 is not a protocol to send emails but to retrieve emails (and quite an old one). To send emails SMTP is used

I am so sorry I was confused @Andoni 

I just try to reply email with a bot.

Email connection can be with pop3 or imap

i connect it with pop3, but i couldnt use Email:reply

to use Email:reply action , do i have to use imap, or it can be done with pop3?

Thanks, I did exactly the same but somehow it gave me the error which i implied in my question details.

Then i thought if i cant do email:reply by connection:Email with pop3.

I dont know what i might do wrong.

Thanks for your replies tho

As I searcged i have to use Email:Loop to reply emails, thats why i connect email first, then do a loop there

But it doesnt reply, just gives error

How about a screenshot of your step, like Andoni did. You mention you did “the exact same thing” but haven’t said if this is a GMail account or other, if it ever worked, etc. We need more information to assist.

@J.Logan Hi, thanks for the reply. I figured out that i was using wrong host and port informations in email:Reply action, i corrected them and it got worked

Glad to hear this, good work!

thank you @Andoni
