March 2021 Summaries

Sending ToS and privacy policy emails is crucial for maintaining audience trust, but these types of emails can be tricky to get right due to their often suspicious nature. Compliance emails tend to look like spam to inbox providers, with high rates of spam complaints, which can damage sending reputations and lead to future emails not reaching inboxes. However, by following best practices such as clear subject lines, telling recipients why they're receiving the email, writing human-friendly copy, staggering email sends in small batches, avoiding busy email sending times, and never sending from the same IP and domain used for transactional emails, businesses can alleviate these challenges. Tools like Postmark Message Streams provide a parallel infrastructure for bulk emails to ensure reliable delivery without hurting send reputations.

Postmark's Message Streams offer a way to separate promotional and transactional email, which can improve deliverability. Separating these types of emails helps avoid issues with spam complaints or deliverability problems caused by sending promotional emails through the same IP pool as transactional emails. Postmark also provides features such as Message Stream servers for each client/customer, allowing for better organization and tracking of sending statistics. Additionally, users can use sub-domains to separate their transactional and bulk Broadcast sending, which helps develop a separate sending reputation for each domain. Postmark has a 99% deliverability rate and offers resources on best practices for sending emails, as well as information on GDPR compliance when sending from the EU.
