Salesforge, Instantly, and QuickMail are three of the most popular platforms for cold email marketing on the market. Each promises automation, adding unlimited email addresses, deliverability, and results for email campaigns , but their approaches and capabilities vary widely. This in-depth comparison explores which one truly delivers on its claims and is best equipped to support effective email outreach in 2025 and beyond.
Salesforge is an all in one cold email platform built for teams, agencies, and founders who want performance without complexity. It combines everything needed to scale outreach, including the ability to add unlimited email accounts, unlimited email addresses, AI powered personalization, deliverability tools, and list validation without the need for third party add ons or extra fees.
Salesforge also includes a powerful warmup engine that operates across multiple languages and domains, simulating natural inbox behavior to build sender reputation over time. It’s designed to work globally and maintain deliverability even at scale, which helps to improve deliverability .
Another benefit of Salesforge is the fact that it is part of the Salesforge ecosystem. This means that Salesforge can be modually combined with other products like Infraforge and Warmforge, or not. This allows its clients to choose, which part of their ecosystem they would like to use, and which part they would rather skip out on. This allows for greater flexibility, especially compared to competitors which include everything in one product and force their customers to only use their services.
Other key advantages include built-in email validation at industry competitive rates and a flat pricing model that avoids per user or per workspace charges. Starting at $40/month per sending account, it allows you to add unlimited email accounts, email addresses, and workspaces without any additional cost , making it ideal for growing teams and agencies.
In short, Salesforge delivers advanced tools, including ai prompts, advanced filters smarter personalization, advanced analytics and fair pricing all in one place.
Instantly.ai has positioned itself as a go to tool for starting teams wanting to send emails fast and in bulk. It includes essential tools like campaign automation, lead list building, some native integrations, features to find warm leads, CRM features, and AI enhanced optimization.
While it performs well for beginners and solo users, the platform has notable weaknesses as you scale. One major drawback is its warmup system, which does not ensure high deliverability, using domains that many in the email community (including agency users on Reddit) have flagged as risky for the long term.
Its personalization relies on small pieces of generic syntax rather than dynamic message generation. This makes everything feel like the same campaigns and may not hold up against tools offering unique email content per lead.
There’s also been increasing skepticism from the community, particularly on Reddit about Instantly.ai’s credibility when it comes to public reviews. Several users have shared that Instantly encourages or even pays users to leave positive reviews, raising concerns over how trustworthy its feedback on platforms like G2 or Capterra really is for business .
To further on these kinds of practices, Instantly also has some problems in regards to how they setup account for their clients. They setup accounts as education email accounts whilst these were not for or related to educational insitutions, which caused these accounts to be banned. This has unfortunately lead to messed up campaigns and hardship for their clients.
QuickMail is a solid choice for teams that prioritize automation, scheduling, and deliverability infrastructure over advanced personalization, including linkedin outreach . It's known for its reliability and simplicity, making it especially popular among solo founders and small sales teams.
One of QuickMail’s strengths is its Deliverability AI, which manages inbox rotation and sending behavior to avoid common spam triggers. It helps maintain domain health across high volume campaigns, allowing for more emails to be sent, and its built-in warmup tool integrates directly into the platform, getting rid of the need for external warmup services.
While it doesn’t offer advanced AI personalization like Salesforge, QuickMail does include a basic message rewriter to help improve email copy. It’s useful for refining outreach but lacks the depth of tools that generate unique, 1:1 emails for each lead.
QuickMail also supports unlimited users under one subscription, making it cost-effective for growing teams. Pricing is based on the subscription plan of the user, allows for sending from multiple channels, and is tailored towards their needs.
In summary, QuickMail offers a dependable platform for sending, automating, and maintaining deliverability, though it may not be the best fit for teams focused on deep personalization or high-scale campaign customization.
Pricing varies based on your need, but the absence of per seat fees makes it more accessible for teams with multiple users.
All tools have build in warmup in their paid plans, Quickmail and Salesforge lead the way in this. The platforms use AI to ensure that its pool is safe and effective, so that when the actual emails are send out, they have high chance of not landing in spam. Instantly, however reportedly has problems with this, by getting lower response rates and a compromised warmup pool, which can leak sensitive information.
Salesforge remains cost-effective with flat pricing, which improves the further it is scaled up. Instantly is the cheapest option of the 3 at the start, but increases in price the more it is used. Furthermore, Quickmail also has higher pricing compared to the others, but this pricing is fixed.
Salesforge offers the most advanced and reliable deliverability setup among the three, making it a favored choice for many businesses looking to reach their ideal clients . Its multilingual warm-up engine, large pool of healthy sending domains, and realistic inbox simulation (including replies, starring, and archiving), which automatically rotate sending, help establish strong sender reputation from the start. Unlike Instantly’s questionable warm-up domains or QuickMail’s more infrastructure-based approach, Salesforge’s deliverability system is fully integrated and optimized for global scale, making it a choice favored by cold email experts for better cold outreach while avoiding vanity metrics and giving users the best shot at consistently hitting the inbox.
There’s credible discussion online (especially on Reddit) suggesting that Instantly pays users for reviews. This may skew feedback on review sites, and create an unreliable narrative surrounding the platform.
Salesforge offers responsive live chat and in app support which you can contact. This provide fast conversations to ensure that any problems are quickly resolved. Instantly’s support varies by providing a large databank with questions as well as in chat support. QuickMail also has chat support which responds to their customers, as well as access to a large databank with frequently asked questions.
