If you are shopping for an email marketing platform, Constant Contact and Klaviyo will almost certainly be on your shortlist. Both are excellent tools. But they are built for different types of businesses, and choosing the wrong one means paying for features you do not need or missing the ones you do.
We use both platforms every day for our clients. Here is our honest, no-fluff breakdown.
The Quick Summary
| Feature | Constant Contact | Klaviyo |

When to Choose Constant Contact
Constant Contact is the right choice when your business is primarily service-based, local, or not heavily dependent on eCommerce revenue. It is designed to be approachable for non-technical users while still offering powerful automation and SMS capabilities.
- →You run a restaurant, salon, gym, real estate agency, or professional services firm
- →You want to be up and running within hours, not days
- →You need SMS and email in one platform without extra costs
- →You want straightforward reporting without a data science degree
- →You are a nonprofit or community organization that qualifies for their discounts
As an authorized Constant Contact partner, SignalForge can get you set up with full onboarding support included at no extra cost.
When to Choose Klaviyo
Klaviyo is purpose-built for eCommerce. If you run an online store on Shopify, WooCommerce, or a similar platform, Klaviyo is in a different league when it comes to revenue attribution, abandoned cart flows, and purchase behavior segmentation.
- →You run an online store with significant transaction volume
- →You want to trigger emails based on purchase history and browsing behavior
- →You need deep integration with Shopify or WooCommerce
- →You have a technical team or agency that can manage the platform
- →Revenue attribution and per-campaign ROI tracking is critical for you
Pricing Compared
Constant Contact starts at $12 per month for up to 500 contacts and scales from there. Klaviyo offers a free plan for up to 250 contacts but pricing scales quickly — 1,000 contacts costs $45 per month, and 10,000 contacts runs $150 per month.
For most small service businesses, Constant Contact offers more value per dollar. For eCommerce businesses doing meaningful revenue, Klaviyo typically pays for itself through better automation and attribution.
