Autoklose vs Loops in 2026: Cold B2B outreach vs opt-in product email for SaaS
Autoklose exists to email people who have not asked to hear from you. Loops exists to email people who already have, whether that is a marketing campaign, an onboarding sequence, or a password reset. Picking between them is really picking which problem you have.
Autoklose
Loops- Loops explicitly states it is not built for cold outreach or lead generation; Autoklose is built for exactly that.
- Autoklose bundles a B2B contact database for finding new prospects. Loops has no database at all, since it only emails contacts your product already knows about.
- Loops publishes a free plan (1,000 subscribers, 4,000 sends/month) and paid plans starting around $49/month. Autoklose has no published pricing at any tier.
- Loops handles transactional email like password resets and receipts from the same account as marketing campaigns. Autoklose has no transactional email capability.
- Loops charges by subscribed contact count with unlimited team seats; Autoklose gates team collaboration behind its Small Business tier.
- Loops ships native SDKs for Node, Next.js, Ruby, PHP, and NuxtJS plus an MCP server; Autoklose does not document comparable developer tooling.
- Autoklose's database and sequencing are aimed at outbound sales reps; Loops is used in production by Framer, Linear, Perplexity, and Reuters for product and lifecycle email.
Autoklose and Loops both live in the marketing automation category but almost never compete for the same buyer, because they are built around opposite assumptions about the recipient. Autoklose is a cold outreach tool: a built-in B2B database plus sequencing, aimed at sales teams contacting prospects who have never interacted with the company before, sold through an unpublished, sales-assisted price. Loops is explicitly not a cold email tool; it unifies marketing campaigns, product lifecycle emails, and transactional sends like password resets for SaaS companies emailing people who already signed up, priced by subscribed contact count with no per-seat cost and a usable free tier. The comparison matters less for teams choosing between them and more for teams that need both: outbound prospecting from one tool, and product communication with the resulting customers from the other.
The tools at a glance
Autoklose
Email automation platform with a built-in B2B lead database, letting sales teams reach thousands of prospects from a single tool.
Autoklose solves a prospecting problem, not a customer communication problem. A sales rep filters the built-in B2B database by industry, size, title, or location, loads the results into a sequence, and lets automated follow-ups run until the prospect replies or the sequence ends. That single-tool workflow, database and sequencer under one login, is the entire value proposition.
Campaign reporting tracks open, reply, and click-through rates by sequence step, and team collaboration lets sales managers see which reps are working which lists once a team is on the Small Business tier or above. As part of VanillaSoft, it also connects into a broader sales engagement stack with lead routing and call management for teams already there.
None of this maps onto what Loops does. Autoklose has no transactional sending, no product-event triggers, and no developer SDKs to speak of, because it was never meant to email your existing customers about a password reset or a feature launch. Its entire reason to exist is contacting people who are not customers yet.

Loops
Unified email platform for SaaS teams covering marketing, product, and transactional email from a single simple interface.
Loops is built around a small set of concepts, contacts, contact properties, events, and event properties, and once you understand those four, you can build any automation the platform supports. That simplicity is deliberate: companies like Framer, Linear, Perplexity, and Reuters run their entire email operation, marketing campaigns, onboarding sequences, and transactional sends, through the same account and domain.
Automations trigger on product events like signup, trial start, or payment, with branching logic and timer steps built visually. Because transactional email lives in the same platform as marketing email, teams stop paying for a separate SendGrid or Postmark account just to send a password reset. Developer support is a real strength: native SDKs for Node, Next.js, Ruby, PHP, and NuxtJS, a CLI, and an MCP server that makes Loops callable from AI agents.
The trade-off for that simplicity is scope. Loops is explicit that it is not designed for cold outreach or lead generation, has no prospecting database, and keeps its feature set intentionally lean compared to enterprise platforms, which limits advanced segmentation and A/B testing on lower tiers. It also puts Loops branding in emails on the free plan, and the free tier caps out at 1,000 subscribers and 4,000 sends a month, tight for a product that is growing fast.

| Email Sends per Month | 4,000 | Unlimited on paid |

Which should you choose?
AutokloseLoopsLoopsLoopsAutokloseAutokloseLoopsIt is tempting to score these against each other feature by feature, but that framing misses the point. Loops says outright it is not for cold outreach, and Autoklose has nothing resembling event-driven product automation or transactional sending. A company evaluating "Autoklose vs Loops" as if they were substitutes is usually really asking a bigger question, whether it needs an outbound sales tool, a product email tool, or both, and the honest answer for a growing SaaS company with a sales motion is frequently both, run as two separate line items rather than one.
Bottom line
If the job is finding new prospects who have not engaged with you yet, use Autoklose. If the job is emailing people who already signed up, whether that is a feature announcement, an onboarding drip, or a receipt, use Loops. Do not expect either one to cover the other's job well; that is not a shortcoming of either product, it is the deliberate boundary each one drew around itself.
Frequently asked questions
Can I use Loops for cold email prospecting instead of Autoklose?
No, Loops states directly that it is not designed for cold outreach or lead generation and has no prospecting database or inbox warmup features built in. Autoklose is purpose-built for exactly this use case with a bundled B2B database and sequence automation aimed at contacts who have not opted in.
Does Autoklose handle transactional email like password resets?
No, Autoklose has no documented transactional email capability; it is built around sales sequence automation to prospects, not system-triggered messages to existing users. Loops handles transactional sends like password resets and receipts from the same account as its marketing and lifecycle email.
Is Loops a good replacement for Autoklose if my company also does outbound sales?
Not as a full replacement: Loops has no lead database and is not built for prospecting people outside your product, so a sales team doing outbound still needs a tool like Autoklose for that half of the workflow. Many growing SaaS companies run both, Autoklose for prospecting and Loops for everything after signup.
Why does Loops charge by contact count instead of per seat like Autoklose's team tiers?
Loops prices by subscribed contact count with unlimited team seats on every plan, which keeps cost predictable as headcount grows without adding to the bill. Autoklose gates team collaboration behind its Small Business tier, and since its pricing is unpublished, it is unclear whether that tier itself scales per seat.
Does Autoklose offer a free tier like Loops does?
Autoklose does not publish a free tier; all three of its pricing tiers, Starter, Small Business, and Enterprise, are listed as contact for pricing. Loops offers a genuine free plan covering up to 1,000 subscribers and 4,000 sends per month with all features included, though with Loops branding in the email footer.
Which tool has better developer support, Autoklose or Loops?
Loops is clearly the stronger choice for developers: it ships native SDKs for Node, Next.js, Ruby, PHP, and NuxtJS, a CLI, and an MCP server for AI-agent workflows, with an npm package seeing 251K weekly downloads. Autoklose does not publish comparable API documentation or developer tooling.
