Reviewed by Switchpoint Editors ·
Contender A
Customer.io
Event-driven messaging for product-led teams — the technical upgrade from ActiveCampaign.
- SaaS and product teams that want behavior-triggered email, SMS, and push driven by their own data.
- Essentials from $100/mo for 5,000 profiles. Premium from $1,000/mo for larger volumes.
Best for
Pricing
Pros
- Real event-based triggers — react to anything your product sends
- Best-in-class workspaces, branching, and A/B logic
- Email + push + SMS + in-app in one workflow
Trade-offs
- Starts at $100/mo — not for hobby projects
- Requires developer setup to send events; not a drag-and-drop marketer tool
Contender B
Omnisend
Klaviyo's closest ecommerce rival with email, SMS, and push in one bill.
- Shopify and WooCommerce stores under ~50k contacts that want pre-built ecommerce flows without Klaviyo's price curve.
- Free up to 250 contacts / 500 emails. Standard from $16/mo, Pro (unlimited email + SMS credits) from $59/mo.
Best for
Pricing
Pros
- Pre-built abandoned cart, browse abandon, and post-purchase flows out of the box
- Bundled SMS and web push in the same plan — no separate add-on
- Pricing is consistently 20–40% under Klaviyo at the same contact count
Trade-offs
- Segmentation is less granular than Klaviyo's predictive analytics
- Reporting is simpler — fine for SMB, thin for data teams
