Guidelines for Sending Targeted, Automated B2B Cold Emails Using Maildoso
Maildoso permits targeted, automated B2B cold email campaigns under specific conditions. These guidelines ensure compliance with Maildoso's terms and help maintain the effectiveness of your email outreach efforts. See also What are the best practices for configuring domains for Maildoso email campaigns? for the domain side of compliant sending.
Overview of Permissible B2B Cold Email Campaigns
Targeted B2B cold email campaigns are allowed when they are directed at relevant corporate business addresses and adhere to Maildoso's best practices. This includes campaigns for promoting services such as SaaS or other business offerings.
Best Practices for Compliance
To ensure your campaigns comply with Maildoso's terms, follow these best practices:
Verify Email Addresses: Use verified and accurate email addresses to minimize bounce rates.
Include an Unsubscribe Option in the email body: Every email must include a functional unsubscribe link or clear opt-out instruction in the message body. Maildoso's sending relay strips List-Unsubscribe/List-Unsubscribe-Post headers on every plan (this is intentional, not configurable per account), so a header-based unsubscribe never reaches the recipient — the body link is the only mechanism that works. See Does Maildoso support List-Unsubscribe (one-click unsubscribe) headers? in the Help Center for details.
Maintain Low Bounce Rates: Monitor and manage your email lists to keep bounce rates low, aiming for a threshold of less than 2%.
Follow Sending Volume Guidelines: Adhere to Maildoso's recommended sending limits to avoid being flagged for spam-like behavior — see What's the daily email limit per email account?
Stay B2B-Only: Maildoso is a B2B-only service. Do not send to personal/consumer addresses (e.g. gmail.com); doing so is likely to land in spam and can result in suspension of service under Maildoso's terms of use.6. Keep Emails Lightweight: Avoid using rich HTML emails with multiple links, images, and buttons for cold outreach. Instead, focus on simple, personalized emails with minimal HTML elements and limited links to improve deliverability and engagement rates.
Avoid Overloading with Images and CTAs: Emails heavy on images and call-to-action buttons may trigger spam filters. Use text-based content with a clear and concise message to maximize effectiveness.
Understand Maildoso's Limitations: Maildoso does not certify the sources of your email lists, the countries of your recipients, or your complaint rates. Additionally, policy exceptions cannot be approved. Ensure your email lists are clean and compliant with applicable regulations.
