As e-mail marketing professionals, we are bombarded with numbers ??? sent, bounced, opens, clicks, hard bounces, soft bounces, unsubscribes and complaint rates. But we are still missing one of the most criti颅cal metrics: How many of our e-mails actu颅ally reach customer inboxes?
We must step back and take a look at the deliverability landscape. The major providers that make up the majority of e-mail marketing lists have tightened delivery requirements. Yahoo, AOL and MSN/Hot颅mail have all implemented authentication technology and coupled that with reputa颅tion evaluation. We must now prove to e-mail providers that we belong in the inbox, vs. the bulk folder. 数据挖掘研究院
To determine true inbox delivery rate (IDR) you will need to know e-mail sent, e-mail bounced, blackholed messages and seedlist delivery rate.
For e-mail bounced, some messages will not bounce for several days. The number and duration of retries before marking as a bounce is a setting that is configurable in your mail transfer agent. The industry stan颅dard for retries is a 72-hour period. 数据挖掘研究院
Blackholed messages are e-mails deleted with no record and are commonly found at corporate domains. A good way to determine this number is to look at all domains where you delivered more than 25 messages but had no bounces, opens or clicks. You may catch some good domains, but cancel those with the smaller domains you did not choose. 数据挖掘研究院
Seedlist delivery rate, a test to estimate delivery rate to your top domains, should be used as a guide to inbox delivery but not a sole source of data. Since we have enough real data, you can feel confident using your seedlist delivery rate as a conservative total.
To calculate your true IDR, identify your blackholed messages by calculating the number of messages sent to domains with greater than 25 recipients with zero opens, bounces and clicks. Then determine your number of unblocked messages by sub颅tracting your failures from messages sent and then blackholed messages from that number. Finally, multiply the number of unblocked messages by the seedlist delivery percent to find your true IDR.
