==================
Right now i am using a smtp from google to send email and all its ok. but now a new requeriment is sending email with salesforces, there is a extension or someway to connect salesforce mailing with limeSurvey?

thanks.

I don't think that there is a an extension for this and I have no idea how salesforces works in terms of sending emails.

However, you can always create your own token table, then create your own token links via excel and import them into salesforce and send them this way.

i am new using limeSurvey you have any link to help me out reading how i can do that? i dont think this is what i need but maybe is a workaround.

Did you read the manual?
