Loops Review 2026: Pricing, Features, Pros & Cons
Almost every SaaS ends up paying for email twice — once for a transactional API and once for a marketing platform, with two audiences that never quite agree. Loops collapses that into one tool and bills on subscribed contacts instead of on sends. That one pricing decision is what makes it obviously right for some products and obviously wrong for others. Here is the honest read on the free plan's real limits, the slider that replaces published pricing, and where Resend, Customer.io and Klaviyo still win.
Quick Verdict
Best for: SaaS products that email an actively managed contact list often, and want transactional and marketing mail in one place. Not for: large lists mailed rarely, e-commerce flows, or teams that need Customer.io-grade journey branching.
What Is Loops?
Loops is an email platform built for software products rather than for newsletters or storefronts. The defining choice is scope: marketing campaigns, onboarding sequences and transactional mail — receipts, password resets, product triggers — all run through the same audience, the same editor and the same analytics. Most teams reach that state by wiring two vendors together and reconciling the difference by hand.
The second defining choice is the billing basis. You pay for subscribed contacts, and on paid plans sends are not metered and transactional email costs nothing extra. Unsubscribed contacts do not count toward the limit. Team seats are free at every tier, which quietly removes the usual argument about who gets access to the email tool.
Its customer list tells you exactly who it is for: Linear, Framer, Perplexity, Clerk, Replicate, Modal and Spline are the names on the pricing page — developer-facing products with engaged user lists and high send frequency. That is the profile the pricing model rewards. Invert it — a 100,000-record list you mail once a quarter — and the same model is the most expensive option on the table.

Add it to the marketing category — a free listing publishes after review, and it is the same page ChatGPT, Perplexity and Google read when someone asks for a recommendation. Want it live in minutes with a Verified badge instead? That option is on the form, one-time, no subscription.
Loops Pros & Cons
✓ Pros
- •One tool for both jobs: marketing campaigns and transactional email (password resets, receipts, onboarding triggers) run through the same platform, the same audience and the same analytics, which is the split that normally forces a SaaS to buy two products
- •Pricing is charged on subscribed contacts, and sends are not metered on paid plans — so a product that emails its users often is not punished for it, unlike per-send or per-credit pricing elsewhere
- •No per-seat fee at all: you can invite the whole team, including a contractor who just needs to check a campaign, without a line-item consequence
- •Unsubscribed contacts do not count toward the contact limit, so a list that churns does not quietly inflate the bill the way it does on tools that bill on total records
- •The free plan is a genuine build tier, not a demo: 0–1,000 subscribed contacts and up to 4,000 sends in any rolling 30-day window, with all features included rather than the usual feature gating
- •Rate limits are stated openly — 10 emails per second on free, up to 1,000 per second per team on paid — and over-limit mail is queued rather than dropped, which matters for launch-day bursts
- •The customer list is a credibility signal in the developer-tools segment specifically: Linear, Framer, Perplexity, Clerk, Replicate, Modal and Spline are all named on the pricing page
- •No credit card to start and the team can be invited during evaluation, so the buying decision can be made by the people who will actually operate it
✗ Cons
- •There are no published price points. Paid pricing is quoted by a contact-count slider on the pricing page rather than fixed tiers, so you cannot budget from the marketing site alone — you have to model your own contact count first
- •Contact-based pricing is the wrong shape for a large, rarely-mailed list: if you have 100,000 contacts and send quarterly, you pay for all of them every month while a per-send tool would charge you four times a year
- •The free plan's 4,000 sends is a rolling 30-day window, not a monthly reset, so a single heavy onboarding week can lock you out for weeks rather than until the 1st
- •Free sends carry a "Powered by Loops" footer, which rules the free tier out for anything customer-facing at a company that cares about brand surface
- •It is positioned for SaaS and does not pretend otherwise — e-commerce flows, SMS, product feeds and revenue attribution are Klaviyo's territory and are not the job here
- •Behavioural segmentation and journey logic are deliberately simpler than Customer.io's, which is the trade for the clean interface; complex lifecycle branching will hit the ceiling
- •Deliverability is on shared infrastructure by default, so if you have a poisoned domain reputation or need dedicated IP control from day one, this is a longer conversation than the signup flow suggests
- •Being a younger platform, the integration surface is thinner than the Mailchimp or Klaviyo ecosystems — check your specific stack before committing, not after

Loops does not publish fixed paid tiers. The paid price is generated by a subscribed-contact slider on its pricing page, so the figure you see depends entirely on the contact count you enter. Details above reflect Loops' published pricing page and FAQ as of September 2026 — check your own contact count against the slider before committing.

Who Should Actually Buy Loops
Buy it if: you run a software product with an engaged user list you email often; you are currently paying two vendors for transactional and marketing mail and reconciling the audiences by hand; per-seat pricing has been an obstacle to letting the right people near the email tool; or your list churns and you are tired of paying for records that already unsubscribed.
Skip it if: your list is large and rarely mailed, where per-send pricing will simply cost less; you are running e-commerce flows that need product feeds, SMS and revenue attribution — that is Klaviyo's job; or your lifecycle logic needs deep conditional branching, where Customer.io is a genuinely more capable engine.
Frequently Asked Questions
How much does Loops cost in 2026?
Loops charges on subscribed contacts rather than on emails sent. The free Early Stage plan covers 0–1,000 subscribed contacts including exactly 1,000, with up to 4,000 emails in any rolling 30-day window counting marketing and transactional sends together, and it includes every feature plus a "Powered by Loops" footer. Above 1,000 contacts the price is quoted by a slider on the pricing page keyed to your contact count — there are no published fixed tiers, so you need your own contact number before you can budget. Paid plans do not meter sends, do not charge separately for transactional email and do not charge for team seats.
Is the Loops free plan actually usable?
Yes, with one trap. Every feature is included — this is not a gated demo — and 1,000 subscribed contacts is a real early-product list. The trap is that the 4,000-send allowance is a rolling 30-day window, not a monthly reset. A launch week that fires a welcome sequence plus a campaign at a 900-person list can consume most of the allowance and leave you throttled for the next three weeks, rather than until the 1st of the month. The other constraint is the Loops footer on free sends, which is fine for internal or beta mail and wrong for anything a customer judges you on.
Loops vs Resend — which should a SaaS pick?
They start from opposite ends. Resend is a transactional email API first, priced on emails sent, with Broadcasts added on top for campaigns; it is the better buy if the overwhelming majority of your volume is system mail and marketing is an occasional afterthought. Loops is a marketing platform that treats transactional mail as included, priced on contacts; it is the better buy if you run onboarding sequences, product announcements and lifecycle campaigns against a contact list you actively manage. The billing basis is the real decision: high sends against a small list favours Loops, low sends against a large list favours per-send pricing.
Does Loops charge for transactional email?
No. On paid plans transactional sending is included at no additional charge, and sends of any type are not metered — pricing moves only with your subscribed contact count. That is unusual: most platforms either bill transactional separately, bill it per send, or push it onto a second product entirely. It is also the single strongest argument for Loops at a product company, because password resets, receipts and trigger emails are exactly the volume that makes per-send pricing unpredictable.
When is Loops the wrong choice?
Three cases. First, a large list you rarely mail — contact-based pricing charges you monthly for 100,000 records whether you send four campaigns a year or four hundred, and per-send pricing will be cheaper. Second, e-commerce: product feeds, abandoned-cart flows, SMS and revenue attribution are Klaviyo's job and Loops does not attempt them. Third, deep lifecycle branching — Customer.io's journey builder handles conditional logic that Loops intentionally keeps simple in exchange for a cleaner interface.
Do unsubscribed contacts count toward the Loops bill?
No. Only contacts marked as subscribed count toward the contact limit, and unsubscribed records stay in the audience without adding cost. That matters more than it sounds on a contact-priced tool: platforms that bill on total stored records quietly convert list churn into a rising invoice, which is the mechanism behind most of the surprise bills people complain about on Mailchimp. Loops does not have that failure mode, though it does have the opposite one — a big list you never mail is still a big bill.
