What Matters More Than Software
Your cold email results depend more on:
- Infrastructure quality: Domains, authentication, warm-up. See our infrastructure guide.
- List quality: Verified, targeted prospect data
- Copy quality: Emails that resonate with your ICP
- Deliverability management: Ongoing monitoring and optimization. See our deliverability guide.
- Follow-up strategy: Multi-touch sequence design
The platform is important but secondary to these fundamentals. A well-managed campaign on any platform will outperform a poorly managed campaign on the "best" platform.

Frequently Asked Questions
Which cold email software has the best deliverability?
Deliverability is primarily determined by your infrastructure (domains, authentication, warm-up), not your software. That said, SmartLead and Instantly have the largest warm-up networks, which helps. At Alchemail, we achieve top-tier deliverability on SmartLead, but the same results are achievable on other platforms with proper setup.
Can I use free tools for cold email?
Free email accounts (Gmail, Outlook.com) are not suitable for cold email due to low sending limits and no custom domain support. Some platforms offer free trials, but serious cold email requires paid tools. The minimum investment is a sending platform ($37-39/month) plus email accounts on Google Workspace or Microsoft 365 ($6-7/month per account).
How many cold email tools do I need?
At minimum, you need: a sending platform (SmartLead or similar), an email provider (Google Workspace or Microsoft 365), and a verification tool (LeadMagic or similar). As you scale, add enrichment (Clay), prospecting (Apollo), and automation (n8n or Zapier) tools.
Should I switch platforms if my current one is working?
No. Switching platforms requires restarting warm-up, rebuilding campaigns, and risking a temporary dip in results. Only switch if your current platform fundamentally cannot support your growth (hitting account limits, missing critical features) or if pricing has become unsustainable.
Is Mailshake still relevant in 2025?
Mailshake was popular in 2020-2022 but has fallen behind SmartLead and Instantly in features, pricing, and warm-up capabilities. It does not include built-in warm-up, charges per user, and lacks unlimited email accounts. For new setups, SmartLead or Instantly are better choices.
