Customer.io Pricing (as of March 2026)
| Plan | Starting Price | Profiles Included | Key Features |
|---|---|---|---|
| Essentials | $100/month | 5,000 | Email, push, in-app, SMS, visual workflow builder, A/B testing |
| Premium | $1,000/month | 15,000 | Dedicated IP, premium support, advanced reporting, data warehouse sync |

Profile-Based Pricing
Customer.io prices based on the number of customer profiles stored in the platform, not on email sends or message volume. This is advantageous for high-volume senders: a company with 5,000 profiles sending 20 emails per profile per month (100,000 emails) pays the same $100/month as a company sending 1 email per profile (5,000 emails).
Essentials Plan Scaling
| Profiles | Monthly Price |

| Up to 5,000 | $100 |
| Up to 15,000 | $200 |
| Up to 30,000 | $300 |
| Up to 50,000 | $400 |
| Up to 100,000 | $700 |
| Up to 250,000 | $1,250 |
| Up to 500,000 | $1,750 |
Additional Channel Costs
Email is included in the base price. SMS and push notifications may incur additional per-message costs depending on volume and destination country. SMS pricing varies by region (U.S. SMS: approximately $0.01-0.02 per message). Push notifications are typically included in the base price.
Cost Comparison with Alternatives
| Tool | 5,000 Contacts | 25,000 Contacts | Key Difference |
|---|---|---|---|
| Customer.io Essentials | $100/mo | $250/mo | Event-driven, multi-channel, API-first |
| Mailchimp Standard | $60/mo | $230/mo | List-based, email-focused, drag-and-drop templates |
| Brevo (SendinBlue) | $25/mo | $65/mo | Email + SMS, cheapest option, less behavioral targeting |
| ActiveCampaign Plus | $49/mo | $149/mo | Email + CRM, good for sales-focused teams |
| HubSpot Marketing Pro | $890/mo | $890/mo | Full marketing platform, expensive but comprehensive |
| Klaviyo | $100/mo | $400/mo | E-commerce focused, Shopify-native integration |
Customer.io is competitively priced against Mailchimp and Klaviyo at similar profile counts, and significantly cheaper than HubSpot. The premium over Brevo reflects Customer.io''s event-driven architecture and multi-channel capabilities.
Editor's Note: We migrated a 45K-subscriber SaaS company from Mailchimp to Customer.io. Setup took 3 weeks (event tracking integration was the bottleneck). Onboarding email sequence completion rates improved from 34% to 52% because we could trigger based on actual product usage, not just signup date. Cost went from $150/mo (Mailchimp Standard at 45K contacts) to $100/mo (Customer.io Essentials, scaling to ~$400/mo as profiles grew). At 45K profiles, Customer.io was actually cheaper than Mailchimp while delivering better behavioral targeting.
