BNবাংলা#Bulk Senders
Bulk senders are organisations that send large volumes of e-mail, such as newsletters, notifications and promotions, to personal mailboxes. Large mailbox providers apply stricter rules to them, including full authentication, a published DMARC policy, easy unsubscribing and low spam complaint rates. The exact thresholds and rules are set by each provider and can change over time. Meeting them is now a basic condition for reaching the inbox at scale. The articles under this tag explain these requirements and how to comply with them.
