Pros & Cons
Keila
Pros
- Fully open source under AGPLv3, with no proprietary premium features, so it can be self-hosted free with Docker.
- Pricing is based on emails sent and every plan includes unlimited contacts, which helps large lists that send rarely.
- The cloud is hosted in Germany and France, which suits organisations with GDPR concerns.
- Several editing modes are available, including a block editor, Markdown, MJML and plain text, plus Liquid personalisation.
- Mail can go out through your own SMTP, SES, Mailgun, Postmark or SendGrid account.
Cons
- There is no free cloud plan, and pricing is listed only for monthly billing.
- Automation is basic, and the template library is small, according to comparison reviews.
- There are few integrations, and the Zapier connector is still in private beta.
- No security certifications are published.
- It has no e-commerce, SMS or landing page builder features.
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.
