Name: Outly
Rating: 4.8 (150 reviews)
Author: Outly

À retenir:

Choose GMass if you want the simplest, most affordable email-only solution that works directly in Gmail ($25/mo starting).Choose lemlist if you need comprehensive multichannel capabilities with advanced visual personalization and don't mind the higher price ($69/mo starting).Choose Outly if you want AI-powered prospection with fonctionnalités like voice cloning, smart commenting, and automated inbox management that balances power with ease of use ($59/mo starting).

After spending several weeks running real campaigns across all three platforms—testing email deliverability, analyzing response rates, and evaluating user experience—the differences between these leading prospection tools became crystal clear:

GMass excels as a Gmail-based extension with unmatched simplicity and affordable tarifs , making it ideal for individual marketers and small teams. However , its email-only focus and limited multichannel capabilities create challenges for businesses seeking comprehensive prospection strategies.

lemlist offers a feature-rich platform for multichannel prospection with advanced personalization , appealing to agences and teams that prioritize branded campaigns. However , its higher price point and steeper learning curve may be prohibitive for smaller organizations or those seeking straightforward solutions.

However, neither of these tools perfectly balances simplicity and safety when it comes to automatisation LinkedIn. And LinkedIn is the best channel today for sales prospecting because cold email response rates have fallen below 1% on average. And LinkedIn gets you a 10%+ response rate on average.

That's why I've included Outly in this comparison.

Outly helps solve critical problems in the prospection space by combining cloud-based reliability with user-friendly design and AI-powered message creation for LinkedIn Automation .

The platform uses dedicated residential IP addresses and offers sophisticated safety fonctionnalités, delivering superior deliverability while running 24/7 in the cloud .

Their unique SalesGPT feature makes crafting effective prospection campaigns accessible even for beginners. This approach has clearly resonated, as evidenced by their growth to over 3,700 users who generate 3-6 meetings per week through their automation.

In this article, I'll compare GMass vs lemlist vs Outly across seven key areas:

Core infrastructure and platform design
Email prospection capabilities
Multichannel prospection fonctionnalités
Personalization options
User interface & ease of use
Deliverability & performance
Tarifs & value

I'll also cover integration capabilities, customer support quality, and specific use cases to help you make the right decision for your prospection needs.

What is GMass?

"Gmail-native cold email with unmatched simplicity"

GMass was founded with a clear mission: to make cold email accessible directly within Gmail, eliminating the need to learn new interfaces or platforms. The company has focused on creating a seamless extension that feels like a natural part of Google's email service.

GMass distinguishes itself through its Gmail-native approach, allowing users to create and manage campaigns without ever leaving their inbox. This creates a frictionless experience, particularly for individuals and small teams already comfortable with Google's ecosystem.

The platform's standout fonctionnalités include its mail merge capabilities, which allow users to personalize emails at scale using Google Sheets, and its straightforward campaign management that makes cold prospection accessible even to beginners.

However, users consistently report that while GMass excels in simplicity and affordability, its capabilities are limited by the Gmail-only approach. Additionally, the lack of a built-in warm-up tool creates deliverability challenges for users sending higher volumes, and its email-only focus means teams requiring multichannel prospection need additional tools. Note that GMass has announced tarifs increases effective January 2026, which will impact the cost advantage it currently holds.

What is lemlist?

"Feature-rich multichannel prospection with advanced personalization" 🚀

lemlist was designed to address the limitations of simple email tools, creating a comprehensive platform for personalized, multichannel prospection campaigns. The platform places particular emphasis on visual personalization and branded messaging.

The platform distinguishes itself through its advanced personalization capabilities, which include the ability to customize images, create personalized landing pages, and coordinate prospection across email, LinkedIn, and calls. This approach makes it particularly appealing to agences and teams that want to create highly branded prospection experiences.

lemlist's standout fonctionnalités include its Lemwarm email warm-up system, which automatically increases sending volume over time to improve deliverability, multichannel campaign capabilities that allow coordinated prospection across platforms, and its advanced personalization options that go well beyond simple text customization.

However, users consistently report that while lemlist excels in advanced fonctionnalités and multichannel capabilities, its standalone platform requires a steeper learning curve compared to Gmail-native solutions. Additionally, the platform's higher price point starting at $69 per user per month with additional costs for extra sending emails ($9/month each) makes it less accessible for smaller teams and individual users.

What is Outly?

"AI-powered prospection that combines reliability with intelligence" 🤖

Outly was founded in 2020 to address critical problems in the prospection automation space: deliverability, ease of use, and effective messaging.

The platform combines cloud-based reliability with user-friendly design, creating a balanced solution for teams seeking both power and simplicity. Unlike Gmail-focused tools like GMass or feature-heavy platforms like lemlist, Outly provides an optimized experience that balances advanced capabilities with intuitive operation.

What truly sets Outly apart is its SalesGPT feature, which uses AI to help users write effective prospection campaigns with minimal effort. This innovation makes sophisticated prospection accessible even to beginners, addressing one of the biggest barriers to success with cold prospection.

Additional unique fonctionnalités include voice note capability for LinkedIn messages, which significantly increases engagement rates by adding a personal touch that text alone cannot achieve, and dedicated residential IPs that substantially improve email deliverability.

Outly's balanced approach to functionality and usability has contributed to its growth to over 4,200 users who generate 3-6 meetings per week through their automation - many of whom migrated from platforms like GMass and lemlist after experiencing limitations with those tools.
