Pros & Cons
Omnisend
Pros
- The Free plan includes email automation, prebuilt ecommerce workflows, unlimited segmentation, popups and landing pages, which is unusual at no cost.
- Every plan, including Free, comes with 24/7 support and free migration, and recent Shopify reviewers describe smooth moves from Klaviyo with helpful account managers.
- Prebuilt flows for abandoned carts, browse recovery, post-purchase and win-backs can combine email, SMS and web push in one workflow.
- The Shopify app has a 4.7 out of 5 rating from more than 3,200 reviews, with frequent praise for quick setup of forms and campaigns.
- At around 10,000 contacts, published comparisons put Standard at about 132 USD a month, below Klaviyo's comparable price.
Cons
- Since May 2026, new customers can only send SMS on Pro and pay per message with no bundled credits, which raises costs for SMS-heavy stores.
- Advanced reporting is only on Pro, and comparisons rate Omnisend's analytics as less deep than Klaviyo's.
- Prices climb steeply with list size, for example Standard goes from 16 USD at 500 contacts to 132 USD at 10,000, and some reviewers report billing surprises.
- Some merchants report account freezes during compliance reviews, deliverability drops, and slow support when these problems occur.
- Its focus on ecommerce makes it a weak fit for SaaS or service businesses.

Cons
