Marketing automation platforms are powerful, but they're also a commitment. Migrating from one platform to another is time-consuming. Picking the wrong one means either living with a tool that frustrates you or going through a painful migration.
This guide gives you a repeatable framework to make the right choice the first time.
Step 1: Define Your Contact Volume & Growth
Pricing scales with contacts. Know your numbers:
- 0-500 contacts: Mailchimp free plan or Brevo
- 500-2,500 contacts: ActiveCampaign Lite ($15-49/mo) or Klaviyo ($20-60/mo for e-com)
- 2,500-10,000 contacts: ActiveCampaign Plus ($49-129/mo) or HubSpot Starter ($20-100/mo)
- 10,000+ contacts: HubSpot Professional ($800/mo) or enterprise ActiveCampaign
Step 2: Map Your Required Features
- Basic email campaigns: All tools do this
- Automation workflows: ActiveCampaign is best. HubSpot is good. Mailchimp is basic.
- Landing pages & forms: HubSpot has the best builder. ActiveCampaign's is decent. Mailchimp's is limited.
- Lead scoring: ActiveCampaign and HubSpot have this built-in. Mailchimp requires a higher plan.
- SMS marketing: ActiveCampaign and Klaviyo support SMS. Mailchimp doesn't.
- Predictive analytics: Klaviyo leads for e-commerce. HubSpot has it on higher tiers.
Step 3: Check CRM Integration
Your marketing automation tool should integrate natively with your CRM. Otherwise you'll spend hours manually syncing data.
- HubSpot CRM → HubSpot Marketing Hub — seamless, native integration
- Salesforce → ActiveCampaign — strong two-way sync
- Any CRM → Mailchimp — Zapier-dependent for most
- Shopify/WooCommerce → Klaviyo — best-in-class e-commerce integration
Step 4: Set Your Budget
Marketing automation pricing varies wildly. Here's what you'll realistically pay as your list grows:
| List Size | ActiveCampaign | HubSpot | Mailchimp | Klaviyo |
|---|---|---|---|---|
| 500 contacts | $15/mo | $20/mo | $13/mo | $20/mo |
| 2,500 contacts | $49/mo | $50/mo | $59/mo | $60/mo |
| 10,000 contacts | $129/mo | $100/mo (Starter) | $99/mo | $150/mo |
