Compliance and Legal Requirements
Ignoring email compliance laws is not a gray area. It is a fast track to fines, blacklists, and destroyed sender reputation.
Cold email is legal in most jurisdictions when done correctly. But the rules vary by country, and violating them carries real consequences.
CAN-SPAM Act (United States)
CAN-SPAM applies to any commercial email sent to recipients in the United States. Penalties: up to $51,744 per email in violation.
Requirements
Clear sender identification
Accurate subject lines (no deception)
Physical mailing address included
Opt-out mechanism that works and is easy to find
Honor opt-outs within 10 business days
What Most Get Wrong
CAN-SPAM does not require opt-in consent for B2B email. You can email someone cold. But you must identify yourself honestly, include your address, and offer a way to unsubscribe.
GDPR (European Union)
GDPR applies to any email sent to recipients in the EU, regardless of where you are located. Penalties: up to 20 million euros or 4% of global revenue.
For B2B Cold Email Under GDPR
You can use "legitimate interest" as your legal basis
Document your legitimate interest reasoning
Include a clear privacy policy link
Respect the right to be forgotten
Never use purchased lists without verified consent
Maintain data processing records
What Most Get Wrong
GDPR does not ban B2B cold email. It requires a lawful basis for processing personal data. Legitimate interest is an accepted basis for B2B prospecting. You must be able to explain why contacting this specific person serves a legitimate business purpose.
CASL (Canada)
CASL is one of the strictest email laws in the world. It applies to any commercial email sent to Canadian recipients. Penalties: up to $10 million per violation.
Requirements
Express or implied consent required before sending
Implied consent expires after 2 years
Clear sender identification
Functional unsubscribe mechanism
Record keeping of consent sources and dates
What Most Get Wrong
Under CASL, you have implied consent to email someone if they published their email address and your message is relevant to their published role. A B2B email to a business address published on a company website can qualify as implied consent. But document everything.
Compliance Best Practices
Practical Compliance Setup
Add your physical business address to every email signature
Include a one-click unsubscribe link in every cold email
Maintain a master suppression list across all campaigns and tools
Process unsubscribe requests the same day they arrive
Document your legitimate interest basis for any EU prospects
Never email personal email addresses for cold B2B outreach. Always use business addresses
Never email anyone who has previously opted out
Most cold email platforms handle suppression lists and unsubscribe links automatically. Firstsales.io includes unsubscribe management, suppression list maintenance, and compliance tracking across all campaigns.
Key Takeaway
Compliance is not optional. The rules are clear, the penalties are real, and the tools to stay compliant are built into every legitimate platform. Follow the rules, document your process, and never cut corners on consent or opt-outs.
Frequently Asked Questions
Everything You Need to Know
About Cold Email in 2026
Quick answers to the most common cold email questions. From deliverability to scaling, we've got you covered.
Start with 5-10 per inbox per day for new accounts. After 2-3 weeks of warm-up, scale to 35-50 per inbox. If you need to send 500+ emails per day, use 10-15 warmed inboxes and rotate sends across all of them. Never push a single inbox beyond 50 cold emails per day.
The average reply rate across all cold campaigns is 3.43%. A 'good' reply rate is 3-8%. Top performers consistently hit 8-15%. Rates above 15% are possible with excellent targeting and trigger-based personalization but are not typical at scale.
Keep cold emails between 50-125 words. Some studies suggest up to 150 words for certain B2B audiences. Shorter emails consistently outperform longer ones. If you need more than 125 words to make your point, your message is not focused enough.
Plain text. Always. HTML emails with logos, images, and formatted layouts trigger spam filters and look like marketing emails. A plain text email from one person to another is what cold email should look like. The only exception is your email signature, which can include basic formatting.
4-7 follow-ups is the sweet spot. 42% of replies come from follow-ups rather than the first email. Space them at Day 3, Day 7, Day 14, Day 21, and Day 30. Each follow-up should add new value, not just 'bump' the thread.
Tuesday, Wednesday, and Thursday are the best days. Best times are 8-10 AM and 2-4 PM in the recipient's timezone. Avoid Monday mornings and Friday afternoons. Wednesday tends to show the highest engagement across most studies.
Yes. Sending cold email from a new inbox without warm-up will land you in spam immediately. Warm-up takes 14-21 days minimum. Keep warm-up running alongside your cold campaigns permanently. Tools like Firstsales.io include warm-up for free with all plans.
Inbox placement rate measures the percentage of emails that land in the primary inbox versus spam or tabs. The global average is 83.1%. This is different from delivery rate (98.16%), which only measures whether the server accepted the email. An email can be 'delivered' but still land in spam.
Set up SPF, DKIM, and DMARC authentication on your domain. Use secondary domains for cold outreach. Warm up new inboxes for 14-21 days. Keep bounce rates under 2%. Verify your email list before sending. Avoid spam trigger words. Send plain text emails. Keep volume consistent.
Yes, in most jurisdictions when done correctly. In the US, CAN-SPAM allows cold B2B email with proper identification and opt-out mechanisms. In the EU, GDPR allows B2B outreach under legitimate interest. In Canada, CASL requires express or implied consent. Always include your business address and an unsubscribe option.
Cold email targets a specific person with a relevant, personalized message and includes identification and unsubscribe options. Spam is unsolicited bulk email sent to purchased lists without personalization or proper opt-out mechanisms. The difference is intent, targeting, and compliance.
Cold email typically costs $30-$50 per lead, making it one of the most cost-effective B2B channels. This includes tool costs ($28-$269/month for a platform like Firstsales.io), data costs ($49-$500/month), and infrastructure costs ($150-$200/month for domains and inboxes).
No. Purchased lists contain invalid addresses, spam traps, and unverified contacts. Bounce rates skyrocket when using purchased lists, which damages your sender reputation. Build your list through research, networking, and organic lead generation instead.
Keep subject lines to 1-5 words for mobile or 6-10 words for desktop. Use lowercase. Include the company name or a trigger event when possible. Avoid spam trigger words like 'free,' 'guarantee,' or 'limited time.' Question-based and trigger-based subject lines consistently get the highest open rates.
DMARC (Domain-based Message Authentication, Reporting, and Conformance) is an email authentication protocol that ties SPF and DKIM together. Yes, you need it. Set your DMARC policy to p=reject, which tells receiving servers to reject emails that fail authentication. This protects your domain and improves deliverability.
Track reply rate (most important), positive reply rate, meeting book rate, bounce rate, and spam complaint rate. A good reply rate is 3-8%. Keep bounce rate under 2% and spam complaints under 0.1%. Measure pipeline generated monthly to connect email activity to revenue.
AI can draft cold emails, but human review is required. AI excels at research, first drafts, and timing. Humans excel at judgment, tone, and nuance. The best approach is a hybrid: AI researches and drafts, human reviews and approves. Fully automated AI emails tend to sound generic and perform worse than human-reviewed AI drafts.
It depends on your needs and budget. Firstsales.io offers the best value with plans starting at $28 per month, unlimited email accounts, free warm-up, and free list cleaning. Instantly.ai works for high-volume senders but costs more ($97-$358/mo). Apollo.io combines data and sending but limits features at lower tiers.
Add inboxes, not volume per inbox. Each inbox should send 35-50 emails per day maximum. Use 3-4 inboxes per secondary domain. Keep warm-up running permanently. Verify every list before sending. Monitor bounce rates and spam complaints daily. Scale gradually, adding 5-10 sends per day per inbox.
