Email Deliverability Lookup: Enhance Your Email Campaigns

Regularly checking your email address and domain names against known spam and cyber threats is a crucial step to improving your email deliverability rate. For example, the renowned international organization Spamhaus Project offers several DNS-based blocklists that are used by ISPs and email servers to filter out unwanted emails and malware. Additionally, tools like Talos Intelligence (by Cisco) offer reputation lookups to see if your email addresses and domains are flagged as spam or associated with malicious activities.

Another key step to optimizing your deliverability rate is ensuring that you have a clean, accurate email list. For example, if your email list includes mistyped, inactive, or nonexistent email addresses, or if people unsubscribe from your emails without letting you know, your email deliverability will suffer. Implementing double opt-in is a great way to avoid this issue and ensure that all new subscribers have opted in to receive your emails.
