How much does Klaviyo cost by list size?
Free up to 250 contacts/500 emails. $20 at 500, $60 at 5K, $175 at 15K, $500+ at 50K, $1,000+ at 100K. SMS roughly doubles all of those.
Email pricing tiers
Klaviyo's pricing scales by number of active contacts (anyone who received an email in the last 30 days). Approximate 2026 monthly costs: 500 contacts = $20, 1,500 = $30, 5,000 = $60, 10,000 = $135, 15,000 = $175, 25,000 = $300, 50,000 = $500, 100,000 = $1,000+. Above 100K, custom pricing.
SMS adds another line
Klaviyo SMS is priced separately by sent message volume + per-contact storage. A brand sending ~2 SMS/contact/month to a 10K-contact list runs ~$200-$350/mo on SMS alone. Add to email cost.
The upgrade cliffs to plan for
Two unpleasant jumps: 10K-25K (price doubles), and 50K-100K (doubles again). At those thresholds, brands often question Klaviyo and look at Omnisend (cheaper, less powerful) or staying on Klaviyo and pruning the list aggressively to stay below the cliff.
