You may want to send an email to one of your contacts through ActiveCampaign because you are able to use personalization tags (including confirmation links). This document will walk you through how to send a one-to-one email from the Contacts Overview page and Contact Record.
Sending from the Contacts Overview:
Click “Contacts” in the top menu to navigate to the Contacts Overview.
Search for the contact.
To the right of the contact's information, you'll see an “Email” button.
Click it to open the contact record and begin composing your message.
Sending from the Contact Record:
Open a contact record by clicking the name or email address of a contact.
You can send an email by clicking “Send Email” on the Compose Bar at the bottom of the screen.
Note that you are able to use personalization tags in these one-to-one emails.
You can also use personal emails to begin automations (with the “Opens/reads an email” trigger).
