Experts and marketers broadly agree that cold email prospecting presents considerable risks, including legal ramifications (GDPR, CAN-SPAM), damage to sender reputation leading to blacklisting, and reduced deliverability. Sharing infrastructure with transactional emails exacerbates deliverability issues. Key alternatives focus on building relationships and providing value: permission-based marketing, content marketing, social media engagement, lead magnets, Account-Based Marketing (ABM), and social selling. Personalizing outreach and ensuring relevance are crucial for improving engagement. Documentation emphasizes the importance of sender authentication (SPF, DKIM, DMARC) and adherence to legal requirements. List scraping and purchasing are strongly discouraged.
