You can enrol multiple contacts in sequences, but be careful – the user experience and deliverability might be diminished.
Here are instructions to enrol multiple contacts in Sequences. But be careful, you may not want to enrol multiple contacts in the same Sequence.
One of the best features of Hubspot's Sales Sequences tool is that you can personalize the Sequence for each person. Hubspot even gives you tips to improve the personalization of each email before you start the Sequence.
