What tools do you use for your email campaigns?

beehiiv.com, if newsletters count as email campaigns.

I'm curious to know if any of you have had a waitlist, how do you go about sending emails to notify customers with access? Is there a way to split up customers in different groups to receive the access? (ex. 100 get access Monday & another 200 get access Wednesday)

I use SendGrid for automatically sending users a welcome message when they sign up on the https://lyrist.app mobile app

We used Sendinblue before but later went to HubSpot. Its easier to have all your customer data in one place.
