Omnisend

Omnisend specializes in email and SMS together, letting you build multi-channel campaigns that reach customers across both inbox and text. The platform offers 250+ pre-made templates to speed up your workflow, plus workflow automation for common scenarios like welcome sequences and cart recovery. It integrates deeply with ecommerce platforms (Shopify, WooCommerce) and works fine standalone if you're just managing an email list.

Coaches who want to experiment with SMS alongside email will appreciate the tight integration and the ease of setting up two-channel campaigns. The template library is extensive and industry-specific, so you're not starting from blank designs. For pure email-only use, you might find better value elsewhere, but if multi-channel appeals to you, Omnisend makes combining email and SMS straightforward.
