Pros & Cons
Constant Contact
Pros
- Live phone and chat support plus one-to-one onboarding are included from the cheapest Lite plan.
- Event registration, ticketing and payment collection are built into every plan, so small organisations do not need a separate events tool.
- The drag-and-drop editor and templates suit non-marketers who need to send newsletters quickly.
- Nonprofits can save up to 30 percent by prepaying for a year.
Cons
- Prices climb steeply with list size, reaching about 160 dollars a month for Standard at 10,000 contacts.
- Custom and ecommerce automations are only on Premium. The lower plans get one or three prebuilt paths.
- A/B testing is limited to subject lines.
- The free plan was removed, and reviewers report billing and cancellation complaints.
- Reviewers describe the interface as dated and needing more clicks than newer competitors.
Klaviyo
Pros
- Deep native integration with Shopify and other stores lets marketers segment on real purchase and browsing data.
- A free plan with 250 profiles and a 20 USD entry plan make it cheap to start.
- Since July 2026, SMS uses dollar-based plans with over 70 tiers, so gaps between plans are smaller and larger plans get lower per-message rates.
- A broad product suite covering reviews, helpdesk, personalization and AI agents can replace several separate tools.
Cons
- Billing by active profiles and uneven tier steps cause cost jumps, for example from 150 USD at 10,000 profiles to 350 USD at 15,000 on the Email plan.
- Many features, such as Reviews, Helpdesk, Personalization and Composer, are separately priced add-ons that raise the total bill.
- Free accounts get email support only for the first 60 days, and reviewers on G2 and Trustpilot report slow or hard-to-reach support.
- New users report a learning curve with segments, event triggers and flow logic.
