Add automated emails

Your sending volume fits both free tiers
Omnisend Free: USD 0/month, up to 250 unique recipients and 500 emails. Klaviyo Free: USD 0/month, up to 250 active profiles and 500 emails. Klaviyo’s active profile count can exceed your send audience. Check required features before choosing.

Is switching worth the cost?
Use two current quotes for the same contacts, sends and channels. Enter all amounts in one currency and on the same tax basis. Enter 0 where no additional cost applies.
Calculation: 12 × monthly cost + other annual costs. Include your own time, migration help and overlapping subscriptions in other costs. The model assumes a constant monthly cost and predicts no sales increase. Amounts are not sent in the calculator measurement event.
