If your email campaigns are not found in the spam or junk folders, your subscriber’s internet service provider (ISP) may be blocking one of Benchmark’s IP addresses. Benchmark sends from several alternating IP addresses so it is necessary for your subscriber to whitelist each Benchmark Email address in order to receive future campaigns.
It is also possible that your their email service (Gmail, Yahoo, AOL) may have quarantined the email. This means they had kept the email to themselves as they believe the email to be very malicious. We can not easily determine this or verify this as we are sometimes not notified or informed.
Please contact Benchmark Email Support so that we may investigate and possibly determine the cause.
