Instantly
Instantly isn't just another email sending platform – it's the command center for serious cold email operations. What sets it apart is its unique ability to warm up email accounts and maintain sender health while managing high-volume campaigns. When deliverability makes or breaks your entire outreach effort, Instantly serves as your first line of defense.
Smartlead
Consider Smartlead your scaling ally. It is the toughest competitor of the instantly. While Most tools focus on sending emails; Smartlead excels at giving the opportunity to business developers to integrate the platform into their businesses. It is a must- go tool for those who really want to cold email at an advanced level.
Apollo
Apollo represents the evolution of prospect research. Rather than spending hours manually gathering contact information, Apollo serves as your intelligence hub, providing enriched data about your potential prospects. The real power lies in its ability to surface information that helps you identify decision-makers who are actually in a position to respond to your outreach. Also it is quite cheap compared to the other options like zohocrm and other private data source providers
Clay
Clay transforms how we think about data enrichment. Unlike basic scraping tools, Clay excels at building comprehensive prospect profiles by connecting dots across multiple data sources. This is crucial because personalization is only as good as the data that powers it. Clay ensures you're working with rich, accurate information that makes your outreach more relevant and compelling.
Million Verifier
Think of Million Verifier as your insurance policy. Email verification might seem like a minor detail, but sending to invalid addresses can poison your entire email reputation. Million Verifier's sophisticated verification system protects your sender reputation while ensuring the leads that you are trying to outreach are invalid and you can send them email without being afraid.
LeadMagic
Even though data providers give you a lot of lead information, They also miss a lot potential client informations as well. Lead magic help markers find the unfoundable datas with their system. Its power lies in its ability to identify decision-makers within organizations, saving countless hours that would otherwise be spent navigating company hierarchies. When combined with other tools in this ecosystem, it becomes a crucial part of a sophisticated prospecting operation.
ScaledMail
ScaledMail is a private dedicated Outlook account provider. Its foundation is pretty strong and the team behind it works very intelligently. If you don’t want to have so many problems when reaching out to Outlook accounts (most of the Outlook users are corporate companies that are high level). It is more expensive than other options, but it is always better not to leave the opportunities on the table.
CheapInboxes
CheapInbox is a Google reseller. They can provide the inboxes for a way cheaper price. They buy Google Workspaces from other countries and make these accounts like official US workspace accounts. And it works as well as the original ones. They also set everything up for you so you don’t need to fumble around with domain and account setup. It is just $3 per account.
Mailreef
Mailreef is a private, dedicated SMTP. This advanced tool can help you excel beyond the competition in cold email, if used and controlled well. It provides a dedicated SMTP service, ensuring that no one affects the deliverability of your inbox. They give you 1 domain and you can create as many accounts as you want from that domain with their infrastructure. The price of it is around 250-300 dollars. You can send thousands of cold emails without considering the issues of deliverability and others that you would normally have.
Email Guard
Email Guard is your reputation sentinel. It continuously monitors your email sending patterns, domain health, and inbox placement rates. In a landscape where a single mistake can damage your sending reputation for months, Email Guard provides the monitoring and protection necessary for professional-grade operations. Especially after Outlook made it harder to send cold emails to Outlook accounts, Email Guard has become our savior by providing the inbox placement test feature. It shows you if any of your inboxes cannot land Outlook accounts, and you can use a different account instead.
N8N
N8N represents the future of workflow automation in cold email outreach. Unlike basic automation tools, N8N allows you to create sophisticated workflows that connect different parts of your outreach ecosystem. You can integrate each of these tools that I mentioned in this doc with N8N. You can be your own software developer in 2025 with N8N.
GPT
Of course, GPT must be in the list in every doc like this. There are no limits to using GPT in cold emails, but I will talk about a couple of them. You can find the pain points of each of your lead with the help of GPT and find the right solution with your cold email. Also rather than choosing between personalization and volume, GPT enables sophisticated content generation that maintains a human touch while operating at scale. This represents a fundamental shift in how we balance personalization with efficiency.
Claude
Claude is a human-like GPT. Sometimes it is better than it. But I use it to craft an email copy for my campaigns. It is way better to produce humanly content. You can easily implement it in clay with the API and use it at the end of your table as a shot enrichment.
Apify
Apify revolutionizes how we gather and process prospect information. Its web scraping and automation capabilities enable you to build rich prospect profiles at scale, providing the raw material needed for truly personalized outreach campaigns. You can also scrape Apollo leads with Apify without paying an excessive price for Apollo itself. There are so many scraping options in Apify; just check it out from the link above.
Serper dev​​
Serper is the cheapest way to find any Google- related data. We generally use it to find the local leads. Because apollo and other sources are not that good to find local businesses every time. Use the power of Serper dev and scrape whatever category you want for your lead list building.
Trigify
Trigify is a social intent collector. You can make your offer more intent-based with this amazing tool. It is very new but has a huge potential for the future. I know the founder and they are willing to develop it for cold email outreach users. You can find who is following specific influencers that produce content about what you sell and so on and so forth. When you start thinking about the opportunities, it is countless.
