IOS & Android
To invite participants to your poll just tap the share icon (add participants) at the top right corner of your already created poll. The menu will then give you the option to add invitees via email, WhatsApp, Messenger etc. Or you can just copy the poll link, and share it in any channel you prefer.
A great way to speed up the invitation process is to connect your phone address book (under your account settings). You can then select to invite via "email" and your contacts will be listed for you to select.
As Premium user, you can add an individual message to invite participants via Doodle. This is a great way to make the invitation more personal. You can also see the list of invitees directly in the poll table, and send a friendly reminder to those who have not participated in the poll yet
