Mistakes to avoid when choosing between Constant Contact and Klaviyo

Comparing the starter plans only. Both tools usually move you to a middle plan within 6 months. Compare the plan you'll actually use, not the one they advertise.
Ignoring the migration cost. The cheaper monthly fee disappears if migration takes weeks. Ask both vendors for their data-import templates and migration support before committing.
Skipping the integration check. Map your existing stack first, then compare which of these two has native integrations vs. which makes you build a Zapier workflow per connection.
Treating "starts at $X" as the real price. Add seats, advanced features, and payment processing where relevant. Build a 12-month TCO before signing.

Frequently asked questions

Constant Contact starts at $20/month, Klaviyo at $20/month. They are similar at the entry tier, but neither stays the cheapest once you add seats and the features you actually need. Always compare total cost at the plan you'll use, not the starter plan.

Yes, both platforms support data import from competitor systems. Klaviyo typically provides a migration template and dedicated support during the trial period. Confirm the scope of the migration (records, attachments, history) with the vendor before signing.

For teams under 10 users, either platform usually offers an accessible starter plan. The pricier option often justifies the cost at 15+ users via better reporting and admin controls. If you expect to cross that headcount within a year, factor in the plan jump before deciding.

Both Constant Contact and Klaviyo ship iOS and Android apps. The functional gap is in offline mode and how much of the desktop feature set works on phones. Walk through your real daily workflow on mobile during the trial. One will feel native; the other will feel like an afterthought.

Not blindly. Most platforms list 100+ integrations, but only a handful matter for your stack. List your 3 to 5 must-have integrations (accounting, payments, calendar, etc.) and check whether each is NATIVE (not Zapier-only) on both platforms. Native integrations are typically faster, cheaper, and more reliable than Zapier-glued ones.
