Cold email
Cold email is an unsolicited but permission-conscious, personalized outreach email sent to a prospect you have no prior relationship with, for a business purpose. Done well it is targeted and relevant (not bulk spam) and complies with laws like CAN-SPAM and GDPR.
How it works
You build a targeted list, verify it, send personalized 1:1-style messages from warmed mailboxes, and follow up across a short sequence — measuring replies and positive responses, not just opens.
Why it matters
Cold email remains one of the most scalable B2B pipeline channels, but only when deliverability, personalization and compliance are right. Volume without those just burns domains.
How Autocloz handles it
Autocloz runs cold email with warmup, deliverability monitoring, verification and rotation — then lets you add calling, LinkedIn, SMS and WhatsApp follow-ups in the same sequence, all on a free CRM.
FAQ
Is cold email legal?
Yes, when done compliantly. In the U.S., CAN-SPAM requires accurate headers, a valid physical address and a working opt-out. The EU/UK (GDPR/PECR) is stricter and generally expects a legitimate-interest basis and easy opt-out.
How many cold emails can I send per mailbox per day?
Keep new mailboxes low (tens per day) and ramp gradually after warmup. Spreading volume across multiple warmed mailboxes protects deliverability better than blasting one.

Cold email deliverability is the share of your outbound cold emails that actually reach the recipient's inbox (not spam, not blocked). It depends on domain authentication (SPF, DKIM, DMARC), sender reputation, mailbox warmup, list hygiene and content — not just whether the email was 'sent'.
DMARC (Domain-based Message Authentication, Reporting & Conformance) is an email standard that tells receiving mail servers what to do with messages that fail SPF or DKIM checks — and sends you reports. It prevents spoofing of your domain and is now effectively required by Gmail and Yahoo for bulk senders.
Mailbox warmup is the practice of gradually increasing a new email account's sending volume while generating positive engagement (opens, replies, moving mail out of spam) so mailbox providers build trust in the sender before real campaigns ramp up.
Multichannel sequencing is automating a coordinated outreach cadence across more than one channel — for example email, then a LinkedIn touch, then a call, then a WhatsApp follow-up — from a single sequence, with per-channel timing and safety rules.
