Nowadays, a sequence doesn't necessarily need to have an email in it. E.g. it could be purely call based, LinkedIn based, or maybe 2 calls, a LinkedIn inMail, 2 messages, 2 post views, one comment and meeting at an event.
Point being, if we don't have the e-mail id, we should still be able to enroll contacts in a sequence to track the number of contacts reached out to in a specific time period, and follow-up on next steps.
Can we please have the ability to add contacts without email IDs in sequences where we won't even need their email IDs?
