Unsolicited one-to-one or small-batch email sent to prospects with no prior relationship, aiming to start a sales conversation.

Cold email is a low-cost way to open conversations with specific accounts, but poor targeting or excessive volume damages domain reputation, which can push all company email, including invoices and support replies, into spam.

An agency sends from a separate subdomain with SPF, DKIM and DMARC configured, warms it up over three weeks, limits each inbox to about 50 emails a day, personalizes the first line per account and suppresses anyone who opts out.

Rules differ by country: the US CAN-SPAM Act allows unsolicited commercial email with an opt-out, while EU ePrivacy rules and national laws often require prior consent, especially for individuals. Reply rates are usually low, and spam complaints quickly hurt deliverability.

Mailbox providers judge senders on authentication and reputation. Google's sender guidelines require bulk senders of 5,000 or more messages a day to Gmail to authenticate with SPF, DKIM and DMARC, offer one-click unsubscribe and keep spam rates below 0.3%. Under CAN-SPAM, messages need accurate headers, a non-deceptive subject, a physical address and an opt-out honored within 10 business days. Good Email Deliverability is a prerequisite for Outbound Marketing at scale.
