The simple rule
- Service businesses, professional services, B2B: Mailchimp wins on price and simplicity.
- E-commerce, transactional, product-driven: Klaviyo wins on segmentation and revenue attribution.
That is the rule. The rest of this page explains why.
Mailchimp strengths
- Cheap at small list sizes ($13-$30/month for under 2,500 contacts)
- Familiar interface for non-marketers
- Decent automation builder for time-based nurture sequences
- Solid landing page builder if you do not have a separate web team
Mailchimp weaknesses
- Segmentation is shallow compared to Klaviyo
- Revenue attribution requires manual setup
- Customer Journeys can break silently and not tell you
- Pricing scales aggressively after 10K contacts
Klaviyo strengths
- Best-in-class e-commerce integrations (Shopify, WooCommerce, BigCommerce)
- Deep segmentation on purchase behavior
- Revenue per email is a built-in metric
- Flows are battle-tested for cart abandonment, browse abandonment, post-purchase
Klaviyo weaknesses
- Overkill for service businesses with no purchase data
- More expensive at every list size
- Steeper learning curve for non-marketers
Where BayouEdge fits
We set up and run either one. For most Houston small businesses we serve (service-based), Mailchimp is the default. For the Houston e-commerce clients we work with, Klaviyo is the default. We do not have a horse in the race.

Frequently Asked Questions
- What if I already have one and want to switch?
- Migration takes 2-3 weeks. We export the list, rebuild the core flows in the new platform, run both in parallel for a week, then cut over. Cost: $1,500-$5,000 one-time.
- Are there other platforms worth considering?
- ConvertKit for course creators. ActiveCampaign for B2B with complex automation. Customer.io for product-led SaaS. HubSpot if you also need CRM. We work with all of them.
- How much does email cost to run monthly?
- Platform fees: $13-$300/month depending on platform and list size. BayouEdge email engagement: $1,000-$3,000/month on top.
- Can I just use my current platform?
- Usually yes. We only recommend switching if the platform is genuinely failing or pricing has gotten out of hand. Most of the time the platform is fine; the problem is the program.
