If you are using Mighty Network to grow your list but want to import them to your Convertkit so you can set up workflows and send email sequences, our current option is also via Zapier.
They do not have a direct integration with Convertkit. We recommend using Zapier if you want your data transferred to Convertkit. We don't create duplicate contacts, so there shouldn't be any issues with duplicates. You can also set up the triggers in Zapier to set up automation or sequence in your Convertkit account. You can check here 33for the integration. You can also check out our Lunch & Video Series28 to know more about how Convertkit works.
If you have further questions, I recommend you email firstname.lastname@example.org to take a look at your account.
