Customer.io vs Drip: Pricing and Automation Compared

Short answer

Pick Customer.io if your product sends events (signups, feature use, plan changes) and you expect to grow past about 10,000 profiles: from that size its published price is lower than Drip's at every step we read, it includes 1 million emails a month on Essentials, and it adds push, in-app and WhatsApp next to email. Pick Drip if you have a small list (under 5,000 people), sell through Shopify, WooCommerce or Stripe, or want the cheapest way to start: Drip costs $39 a month for 2,500 people, while Customer.io's Essentials plan starts at $100 a month for 5,000 profiles.

Both tools build behavior-triggered email journeys on a visual canvas. They differ in who they were designed for, how they count the people you pay for, and what changes in the bill as the list grows. Prices below were read from customer.io/pricing and drip.com/pricing on 7 October 2026.

At a glance

Where the two products really differ

Who you pay for: profiles versus active people

Customer.io meters profiles, a count that includes people and any objects you model (a company or an account, say). Its billing documentation states that a profile counts for the month if it exists at any point during the billing period, even if you delete it later, so a mid-month cleanup does not lower that month's bill. Extra profiles above your tier cost $0.009 each on Essentials, which Customer.io's billing docs and pricing page both show.

Drip meters active people and says on its pricing page that the cost depends on that count and on the volume of email sent in the month. The two counts are not the same unit, so a list of 10,000 rows in your database can land in different price steps in the two tools. Export your real numbers before you compare quotes.

Channels beyond email

Customer.io's pricing page lists email, push, in-app messaging and WhatsApp, with SMS volume handled as a custom item. That matters when your product is a mobile app or a dashboard where an in-app banner is the natural nudge. Drip's channels are email and SMS plus onsite campaigns (pop-ups and forms on your website). If your whole lifecycle lives in the inbox, the missing push and in-app channels cost you nothing; if you plan to move activation messages into the product later, Customer.io saves a second vendor.

Who the defaults are built for

Customer.io's Essentials card is written around product data: profiles, object types (two on Essentials, ten on Premium) and a data-integration layer. A team that already pipes events from a backend or a CDP will recognise the model at once. Drip's own pricing page speaks in store terms: Shopify, WooCommerce and BigCommerce integrations, ecommerce revenue attribution ("revenue traced back to the email that earned it"), and playbooks such as welcome series, abandoned cart and win-back. Stripe is on its integration list as well, so a subscription product can use it, but the out-of-the-box templates lean toward selling things.

What the entry plans leave out

On Customer.io, the comparison table on the pricing page marks managed deliverability as not included on Essentials (it is included on Premium and Enterprise), and Essentials support is email and community only. Drip's lowest tiers include up to 50 workflows and dynamic segments; chat support shows up at the 10,000-person readout, and free migration with personalised onboarding at the 25,000-person readout.

What each one costs at six list sizes

Both vendors publish a slider or selector, so these are list prices read from the pages on 7 October 2026, billed monthly. Customer.io's steps are its Essentials plan; Drip's are its single usage-based plan. Where one vendor has no step at the same size, the cell says so instead of guessing.

Read the table as three regimes. Below 5,000 people Drip is the cheaper bill, and at 2,500 it is $39 against a $100 floor, which is a real gap for a pre-launch list. Around 10,000 the two are within $9 of each other, with Customer.io slightly lower. Above that the curves separate: at 30,000 Customer.io lists $325 where Drip lists $449, and at 50,000 Customer.io's $505+ compares with Drip's $699, which is the point where Drip also moves you to a sales conversation.

Two things are not in the table. Customer.io charges $0.12 per extra 1,000 emails beyond the 1 million included, which a typical SaaS list never reaches. And if your company has raised under $10 million, Customer.io's Startup Program gives a full year free, so for an early-stage startup the first twelve months can cost nothing at all before the table above applies.

Pros and Cons

Which one to pick, by team

A SaaS team with product events and a list heading past 10,000

Customer.io. It is the lower of the two bills from 10,000 profiles up ($145 against $154 at 10,000, $325 against $449 at 30,000), it keeps push and in-app available for later, and its Essentials plan already includes 1 million emails a month. Budget for the profile definition: model companies as objects deliberately, because every object counts toward the tier.

A pre-launch or bootstrapped SaaS with a list under 5,000

Drip, unless you qualify for the Startup Program. At 2,500 people Drip costs $39 a month and at 5,000 it costs $89, against Customer.io's $100 floor. If you have raised under $10 million, take Customer.io's free year first and revisit the price when it ends.

A product sold through a store or a plugin ecosystem

Drip. Its Shopify, WooCommerce and BigCommerce integrations and order-level revenue attribution are the reason it exists; Customer.io's Essentials card lists only basic data integrations.

A mobile app or a dashboard where in-app prompts matter

Customer.io. Push and in-app messaging are on its pricing page and absent from Drip's.

Bottom line

For a typical funded SaaS startup, Customer.io is the better default: it is cheaper than Drip at every step from 10,000 people that we read, it carries more channels, and the startup year changes the first-year math. Drip is the better pick for a small, commerce-flavoured or tightly budgeted list, where its $39 and $89 steps beat Customer.io's $100 floor and the missing push channel never matters. Neither tool is cheap enough at 50,000 people to stop shopping around: Customer.io shows $505+ and sends you to Premium, Drip shows $699 and a demo button.

Frequently asked questions

Is Drip cheaper than Customer.io?

Only for small lists. On the published steps Drip is lower at 2,500 people ($39 against Customer.io's $100 floor) and at 5,000 ($89 against $100). At 10,000 Customer.io is $145 and Drip $154, and the gap widens from there.

Does Customer.io have a free plan?

No ongoing free plan. Its pricing page offers 12 months free through the Startup Program for companies that have raised under $10 million. Drip also has no free plan, only a 14-day trial with no card required.

What happens to the bill when my list doubles?

On Customer.io, going from 10,000 to 20,000 profiles moves Essentials from $145 to $235. On Drip, 10,000 to 20,000 people moves the bill from $154 to $289. Customer.io also keeps counting a profile for the whole month even if you delete it partway through.
