Email Marketing vs Cold Email: Different Tools
Important distinction: Email marketing services are for sending to people who opted in (subscribers, customers). They are NOT designed for cold email outreach.
If you use Mailchimp, ConvertKit, or any marketing platform for cold email:
- Your account will be banned
- Your domain reputation will be damaged
- You'll violate the platform's terms of service
For cold email outreach, you need separate infrastructure.
ColdRelay is built specifically for cold outreach:
- Separate from your marketing domain — protects your main domain reputation
- $1 per mailbox — dedicated sending infrastructure
- Designed for cold email — not marketing blasts
- SPF, DKIM, DMARC — authentication handled automatically
Use email marketing platforms for your subscribers. Use ColdRelay for your prospects.

FAQ
Which email marketing service has the best deliverability?
ActiveCampaign and ConvertKit consistently rank highest for deliverability. Mailchimp is middle-of-the-road. Brevo varies. Deliverability depends partly on your own sending practices.
Can I switch email marketing platforms easily?
Yes — most platforms allow CSV import of subscriber lists. You'll lose automation history and some segmentation data, but contacts transfer easily. Export before canceling.
How many subscribers do I need before paying?
Most platforms have useful free tiers up to 500-2,500 subscribers. Start free, upgrade when you need automation, better templates, or hit the contact limit.
Is email marketing still worth it in 2026?
Absolutely. Email generates $36 per $1 spent — the highest ROI of any marketing channel. 4+ billion people use email. Social algorithms change; your email list is yours forever.
Email marketing for subscribers. Cold email for prospects. Keep them separate. ColdRelay — cold email infrastructure that protects your marketing domain. $1/mailbox.
