Loops vs Warmly in 2026: $49/month product email vs $10,000/year visitor de-anonymization
The price gap alone tells most of the story. Loops sends email to people who signed up for your product. Warmly identifies the people already browsing your site who have not, and puts autonomous AI agents on them before a rep gets involved.
Loops
Warmly- Warmly's entry price is $10,000/year with a required sales conversation; Loops starts free and its paid tier is roughly $49/month, a gap of over 200x at the low end.
- Warmly de-anonymizes website visitors at the individual person level; Loops has no visitor identification feature, since its contacts already opted in through product signup.
- Loops handles transactional email like password resets in the same account as marketing email; Warmly's own feature list has no transactional email capability at all.
- Warmly's Context Graph unifies site visits, CRM activity, call transcripts, and chat logs into a real-time account view; Loops' data model is limited to contacts, properties, and events you send it directly.
- Loops offers a genuine free tier for up to 1,000 subscribers; Warmly has no free trial or self-serve option of any kind.
- Warmly's full autonomous inbound automation requires its $30,000/year AI Inbound Autopilot plan; Loops' entire pricing model tops out around a $49/month starting point for paid usage.
- Both platforms include API access, and Warmly additionally offers an MCP server, matching Loops' own MCP integration for AI-agent accessibility.
There is a two-order-of-magnitude price gap between Loops and Warmly, and it exists because the two tools automate entirely different moments in the customer journey. Loops runs marketing, lifecycle, and transactional email for a SaaS product's existing users, priced by contact count starting free. Warmly de-anonymizes website visitors down to the individual person, unifies every signal about them into a Context Graph, and deploys autonomous AI agents to engage them, priced from $10,000 a year with a mandatory sales process. A company evaluating both at once is not really comparing tools, it is comparing two completely different line items in a GTM budget.
The tools at a glance
Loops
Unified email platform for SaaS teams covering marketing, product, and transactional email from a single simple interface
Loops is organized around contacts, contact properties, events, and event properties, a model built to reflect real SaaS triggers like signup, trial start, payment, and feature activation directly. The API mirrors that simplicity with SDKs for Node, Next.js, Ruby, PHP, and NuxtJS.
Marketing campaigns, lifecycle sequences, and transactional sends run from one account, priced by subscribed contact count with no per-seat fee, and the free plan covers up to 1,000 subscribers and 4,000 sends a month. Framer, Linear, and Perplexity all run product email through it.
Loops has no visibility into anonymous website traffic at all. It only knows about people once they take an action inside the connected product, which is a fundamentally narrower scope than Warmly's premise of identifying visitors before they ever sign up for anything.
| Feature | Free $0/mo | Paid (contact-based) Starts at ~$49/mo |
|---|---|---|
| Website visitor identification | ✗ | ✗ |
| Transactional email | Limited | ✓ |
| Team seats | Unlimited | Unlimited |
| Self-serve signup | ✓ | ✓ |
Warmly
AI agents de-anonymize website visitors at the person level and autonomously run inbound and outbound GTM across chat, email, and ads
Warmly's differentiating capability is person-level de-anonymization: when a visitor lands on your site, the platform resolves their individual identity, not just their company, enabling immediate, personalized engagement instead of waiting for a form fill. That single capability has no equivalent anywhere in Loops.
The Context Graph unifies site visits, email activity, CRM records, call transcripts, chat logs, and ad engagement into one real-time account view, and autonomous AI agents use that context to decide when and how to engage, operating in a human-supervised model. Customers cite 3x more qualified pipeline and replacing $20,000-$40,000 monthly SDR agency spend.
None of this is available without a sales conversation and a minimum $10,000 annual commitment, scaling to $30,000 a year for full autonomous automation, plus $10,000/year add-ons for GTM Signals and Warm Experiences. There is no self-serve path into Warmly at any price.

Which should you choose?
LoopsWarmlyLoopsWarmlyLoopsWarmlyThe price gap here is not a coincidence, it is the whole story. Loops is priced for a SaaS founder validating a product email integration on a weekend; Warmly is priced for a revenue leader replacing a five- or six-figure SDR agency contract. Neither company built toward the other's price point or use case, and there is no meaningful overlap to resolve.
Bottom line
Choose Loops if you need onboarding, lifecycle, and transactional email for a SaaS product's existing users, on a budget that starts free. Choose Warmly if you have meaningful website traffic converting at a low rate and can justify a five-figure annual commitment to identify and autonomously engage those anonymous visitors, particularly if you are currently spending on an underperforming SDR agency. These serve different budgets, different teams, and different stages of company, not different tiers of the same decision.
Frequently asked questions
Can Loops identify anonymous website visitors the way Warmly does?
No, Loops has no website visitor identification or de-anonymization feature at all. It only knows about contacts once they take an action inside the connected product, such as signing up. Warmly is specifically built to resolve anonymous website visitors down to the individual person before they ever sign up for anything.
Why is Warmly so much more expensive than Loops?
Warmly's pricing starts at $10,000 per year because it is selling enterprise-grade person-level website de-anonymization, a unified Context Graph, and autonomous AI agents, none of which have a self-serve tier. Loops starts free because it is a lightweight SaaS email platform for sending marketing, lifecycle, and transactional email to a product's own existing users.
Does Loops have a free trial the way I might expect from Warmly?
Loops has a genuine standing free plan covering up to 1,000 subscribers and 4,000 sends per month, not just a time-limited trial. Warmly has no free trial or self-serve option at all; every plan requires a sales conversation and a minimum $10,000 annual commitment.
Can Warmly send transactional email like password resets the way Loops can?
No, Warmly's feature set is entirely focused on identifying and engaging website visitors through chat, email follow-up, and ad retargeting. It has no transactional email capability. Loops is purpose-built for transactional sends like password resets and billing notifications alongside marketing and lifecycle email.
Is there any overlap between what Loops and Warmly actually do?
Very little. Both technically send email as part of their workflow, but Loops sends to people who already signed up for your product based on their in-product behavior, while Warmly's email follow-up is one channel among several used to engage anonymous website visitors it has just identified. The starting data and the audience are entirely different.
Should a company use both Loops and Warmly?
It is plausible for a company with significant website traffic and an existing SaaS product with real usage data. Warmly would identify and engage anonymous visitors to convert them into leads, while Loops would separately handle onboarding sequences and transactional email once those leads become signed-up product users.
