Hello @user563289 ,
Which plan you select will want to select will largely depend on what you're wanting to do, besides sending emails. If you're just planning on sending emails, with the usual elements included, then the Email plan will likely suit your needs fine. If you're needing particular integrations, specialized email blocks, advanced automated campaigns and email blocks, and more control over particular sign up forms, then Email Plus may be what you'll need to go with. I'd recommend going through the Plans & Pricing comparison page to get a clear breakdown of what's included in either plan.
