Pros & Cons
Mailchimp
Pros
- Reviewers on G2 and Capterra often praise the template library and easy navigation, which help non-technical users send campaigns quickly.
- Large review base, with a 4.5 rating on Capterra from more than 17,000 reviews and 4.3 on G2.
- Standard includes up to 200 automation flows, predictive segments and generative AI tools at a low starting price.
- Premium adds enterprise SSO, unlimited seats and dedicated onboarding for larger teams.
Cons
- Costs rise steeply with list size. Premium starts at 350 USD a month, and reviewers rank pricing as the top complaint.
- New accounts are billed for unsubscribed and unconfirmed contacts, and going over the plan limit triggers overage fees.
- In January 2026 the Free plan was cut to 250 contacts and 500 sends a month, and automations were removed from it.
- Reviewers on G2 and Capterra say support is slow or inconsistent, especially for integration troubleshooting.
- Essentials limits automation flows to four steps.
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.
