    Earlier today Return Path had a informative webinar about avoiding spam traps and email deliverability.

    The following is a list of tips to help avoid sending email newsletters to spam trap addresses:

    • Do not allow generic addresses and role accounts to be subscribed (webmaster@, abuse@, support@)
    • Remove addresses from your list that bounce (5xx user unknown, access denied)
    • Confirm opt-in new subscribers (send an email and make them click a confirmation link)
    • Block suspicious behavior (many subscriptions from a single IP address)
    • Segment your email into dedicated outgoing IP addresses
    • Use hidden fields in your forms to help detect human vs. bot activity
    • Some people recommend CAPTCHA but those are easily broken (try hard to answer questions that are easy for humans)
    • Audit the lists from data providers and reject compromised lists that don't meet your quality standards
    • Never buy an email list from a 3rd party!
