Loops vs QuickMail in 2026: SaaS product email vs cold outbound with unlimited senders
Loops emails people who signed up for your product. QuickMail emails and LinkedIn-messages people who did not, with unlimited senders and free warmup on every plan. Same category tag, opposite mailing lists.
Loops
QuickMail- QuickMail includes unlimited email senders and LinkedIn accounts on every plan; Loops has no LinkedIn feature and sends only from your product's own domain.
- Loops handles transactional email like password resets alongside marketing email; QuickMail's own feature list has no transactional email capability, since it is a cold outreach tool.
- QuickMail includes free AutoWarmer via MailFlow on every plan to build sender reputation; Loops has no comparable warmup feature since its email goes to opted-in product users, not cold contacts.
- Loops charges by subscribed contact count with a usable free tier up to 1,000 subscribers; QuickMail has no free tier, only a 14-day trial, and charges flat regardless of contact count within plan limits.
- QuickMail has no prospecting database at all; contacts must be imported. Loops also has no prospecting feature, but its contacts arrive organically through product signup.
- QuickMail gates API access behind its $99/month Growth plan; Loops includes API access, via REST API and SDKs, on both its free and paid tiers.
- Loops includes an MCP server for AI-agent accessibility; QuickMail's own data does not describe an MCP integration.
Loops and QuickMail both show up under marketing automation, but the contact lists they work with come from opposite places. Loops sends marketing, lifecycle, and transactional email to people who already use your product, priced by contact count with no per-seat fee. QuickMail runs cold email and LinkedIn sequences to people who have never heard of you, priced flat with unlimited senders and unlimited users starting at $49/month. There is essentially no scenario where a team picks one over the other for the same job; the real question is whether you need both.
The tools at a glance
Loops
Unified email platform for SaaS teams covering marketing, product, and transactional email from a single simple interface
Loops organizes automation around contacts, contact properties, events, and event properties, a model built to reflect real SaaS product triggers: signup, trial start, payment, feature activation. Marketing campaigns, lifecycle sequences, and transactional sends run from the same account and domain, with an API and SDKs for Node, Next.js, Ruby, PHP, and NuxtJS.
Pricing is based on subscribed contact count with no per-seat fee, and the free plan, up to 1,000 subscribers and 4,000 sends a month, is enough to validate an integration before paying. Framer, Linear, and Perplexity all run product email through Loops.
There is no cold outreach angle to Loops at all. It has no LinkedIn integration, no sender warmup feature, and no contact-finding capability, because every recipient in the system opted in by signing up for the connected product.

| LinkedIn automation | ✗ | ✗ |
| Sender warmup | ✗ | ✗ |
| Transactional email | Limited | ✓ |

QuickMail
Cold outreach platform combining email and LinkedIn sequences with free inbox warm-up and unlimited senders
QuickMail, running since 2014, builds its entire pitch around unlimited: unlimited email senders, unlimited LinkedIn accounts, and unlimited users on every plan from $49/month, with no per-sender fee as sending domains are added. Inbox rotation spreads volume across mailboxes automatically to protect deliverability.
Free AutoWarmer via MailFlow runs on every plan without drawing down the monthly send limit, and Deliverability AI can swap underperforming email accounts for healthier ones inside a live campaign. LinkedIn steps run through a Chrome extension requiring an active browser session.
QuickMail has no prospecting database, no product-event triggers, and no transactional email capability. It expects a contact list to already exist, whether imported or connected via Zapier, and its entire workflow is oriented toward reaching people cold, not nurturing existing users.

|---|---|---|---|
| Email senders | Unlimited | Unlimited | Unlimited |
| LinkedIn accounts | Unlimited | Unlimited | Unlimited |
| Free AutoWarmer | ✓ | ✓ | ✓ |

Which should you choose?
LoopsQuickMailLoopsQuickMailLoopsQuickMailThere is nothing to hedge on here: these tools do not compete, because the contact lists they operate on come from opposite places. Loops has zero cold-outreach features by design, and QuickMail has zero product-event triggers or transactional email by design. The only genuinely useful comparison is what each free-tier-or-trial-equivalent lets you validate before paying: Loops gives real usage up to 1,000 subscribers for free, QuickMail gives a 14-day trial with no credit card.
Bottom line
Choose Loops for anything sent to people who already use your product: onboarding, lifecycle nudges, receipts, password resets. Choose QuickMail for anything sent to people who have not, cold email and LinkedIn prospecting with unlimited senders and free warmup baked in. A SaaS company running both outbound sales and a live product should expect to pay for both tools, and treating this as an either-or decision means one half of the business goes unserved.
Frequently asked questions
Can QuickMail send transactional email like Loops does?
No, QuickMail's own feature list has no transactional email capability; it is built for cold email and LinkedIn outreach sequences, not password resets or billing notifications. Loops handles transactional email natively alongside marketing and lifecycle email in the same account.
Does Loops include LinkedIn automation the way QuickMail does?
No, Loops has no LinkedIn integration of any kind. It is strictly an email platform for existing product users. QuickMail includes unlimited LinkedIn accounts on every plan, with connection requests, messages, and InMails run through a Chrome extension.
Which platform is cheaper for a small team?
It depends what you are paying for. Loops has a genuinely free tier up to 1,000 subscribers with no per-seat cost, while QuickMail has no free tier, only a 14-day trial, and its $49/month Starter plan is priced flat regardless of team size but caps at 1,000 uploaded contacts.
Does QuickMail include a prospecting database like some competitors?
No, QuickMail has no built-in lead database; users must import their own contact lists or connect a separate data source via Zapier. Loops similarly has no prospecting feature, but for a different reason, its contacts arrive through product signup rather than requiring import.
Is Loops or QuickMail better for warming up a new sending domain?
QuickMail is the relevant tool here, since it includes free AutoWarmer via MailFlow on every plan specifically to build sender reputation for cold outreach domains. Loops does not need or offer warmup, because its email goes to people who already opted in by signing up for the product, not cold contacts.
Should a SaaS company running outbound sales use both tools?
Yes, that is the realistic setup. QuickMail would handle cold email and LinkedIn prospecting to generate new pipeline, while Loops would separately manage onboarding, lifecycle campaigns, and transactional email for users who have already signed up for the product.
