Pros & Cons

Klaviyo logo
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.

M
MailWizz

Pros

  • The license fee replaces per-subscriber pricing, so costs stay flat as lists grow to large sizes.
  • Unlimited delivery servers across SMTP, Amazon SES, SendGrid, Mailgun, and others, with failover.
  • The Extended license allows agencies to run a white-label multi-customer email SaaS.
  • Built-in A/B test campaigns, autoresponders, recurring campaigns, surveys, and a landing page builder.
  • You keep full control of subscriber data on your own infrastructure.

Cons

  • Installing, updating, and security patching on your own server are your job.
  • Deliverability, IP warming, and SPF, DKIM, and DMARC setup are not managed for you.
  • Reviewers describe the PHP interface as dated.
  • Only one month of Premium Support is included, and longer support requires paid packs.
  • No native SMS or ecommerce abandoned-cart features were found.
