In this feature-by-feature comparison, we dive into two notable SaaS tools in the email warming space: Growbots and Instantly.ai. Each offers unique capabilities designed to enhance your email marketing efforts, but which one is the best fit for your needs? Let’s explore.



    Growbots has established itself as a key player in the realm of email marketing tools, focusing on enhancing the deliverability of emails. While it does not explicitly detail the warm-up volumes or the availability of free tools, it is praised for its ease of use. The platform offers a straightforward setup process that does not require technical expertise, making it accessible to marketers of all skill levels. Customer support is provided via email, ensuring users have guidance throughout their email optimization journey. Growbots’ commitment to user experience and deliverability improvements makes it a contender for those seeking efficiency and reliability in their email campaigns.

    Warmup Inbox


    Instantly.ai stands out for its broad compatibility with various email providers and its emphasis on simplicity and user efficiency. Although it does not disclose specific warm-up volumes, its focus on a simple, intuitive interface with one-click solutions appeals to users seeking minimal setup time and maximum efficiency. The lack of free tools and blacklist monitoring features suggests a streamlined approach, concentrating on core functionalities. With support options including chat and email, Instantly.ai aims to provide responsive assistance to its users. The availability of a free trial allows potential users to experience its features firsthand, contributing to its positive reception as indicated by its ratings on Trustpilot and G2.

    Email Providers and SMTP Compatibility

    Growbots. Demonstrates compatibility with a wide array of email providers, which is crucial for businesses looking to improve deliverability across different platforms.

    Instantly.ai. Also supports various email providers, underscoring its versatility in enhancing email deliverability, though without specifying the extent of its compatibility as comprehensively as Growbots.

    Warm-Up Volume

    Growbots. The absence of specific information on warm-up volumes leaves potential users guessing about the scale at which it can support their email warming needs.

    Instantly.ai. Does not disclose warm-up volume details either, making it difficult for users to compare this aspect directly with Growbots.

    Ease of Use

    Growbots. Its platform is designed for simplicity, offering users an uncomplicated setup process without the need for deep technical knowledge, making it an attractive option for businesses of all sizes.

    Instantly.ai. Prioritizes user experience with a straightforward interface and one-click solutions, effectively reducing the learning curve and enabling quick implementation.

    Free Tools

    Growbots. Does not highlight the availability of free tools within its offerings, which might limit its appeal to users looking for additional value without extra cost.

    Instantly. Similarly, the absence of free tools focuses the platform on its primary service, possibly missing an opportunity to attract users with complementary features.

    Blacklist monitoring

    Both platforms do not mention offering blacklist monitoring, a feature that can be critical for identifying and resolving issues affecting email deliverability.

    API Access

    Growbots and Instantly. Neither platform offers API access, which could be a limitation for businesses looking for more extensive integration capabilities with their existing systems.

    Customer Support

    Growbots. Provides support exclusively through email, which may suffice for many users but could be seen as limiting immediate interaction.

    Instantly. Offers a broader range of support options, including chat and email, potentially providing quicker responses and a higher level of interaction with users.

    Free Trial and Feedback

    Growbots. Offers a trial period to test its services, with mixed reviews indicating varied user experiences across different aspects of its service.

    Instantly. Provides a free trial, allowing users to directly engage with its features. Its average rating on Trustpilot and high rating on G2 suggest a generally positive reception among its user base.


    When comparing Growbots and Instantly.ai, both platforms offer distinct advantages for enhancing email deliverability. Your choice may hinge on specific features such as ease of use, customer support options, or the availability of a free trial to assess the tool’s effectiveness.
