How to Evaluate Cold Email Providers
A framework for comparing providers beyond just price: what to look for in account quality, support, and reliability.
A Framework for Choosing Cold Email Infrastructure
1. Infrastructure Type
Google Workspace, Outlook 365, or custom SMTP? Dedicated or shared?
2. DNS Configuration Quality
Does the provider handle SPF, DKIM, DMARC, and MX record setup?
3. Pre-Warming Availability
Pre-warmed accounts save 2-3 weeks and eliminate $15-20/month per inbox in warmup costs.
4. Support Speed and Quality
WhatsApp or live chat is dramatically more valuable than email-only support with 24-48 hour response times.
5. Track Record and Reviews
Established providers with public reviews carry significantly less risk.
6. Pricing Transparency
No hidden costs for warmup, DNS configuration, or per-email fees.
Bottom line: Price should be the last factor you evaluate, not the first. Infrastructure quality, DNS configuration, pre-warming, support speed, and track record all have a larger impact on your cold email ROI.
