Stephanie Miller's Engagement Matters: Why Good Email Gets Blocked as Bad
1. A solid infrastructure. For either an in-house system or a vendor, check frequently to be sure you know that your infrastructure is sound (e.g., proper reverse DNS, MX records, authentication and volume throttling) and your bounces are managed properly. Make sure you fully understand the metrics used in reporting as well.
2. Low complaints. There's a penalty for irrelevancy in email marketing that doesn’t exist in other channels. It’s called “complaints.” A complaint is registered every time a subscriber clicks the “Report Spam” button. It only takes a few complaints to get all your messages blocked at Yahoo, Gmail or corporations (which use many of the same data sources). Subscribers complain when they're not happy or interested in your messages, even if they're customers and gave you permission. They complain even when they claim to love your brand.
Yikes! Imagine what would happen if Yahoo or another major ISP blocked all your messages for the next 30 days (the length of time many deliverability failures take to correct). Revenue would drop like a brick and you’d be under the spotlight to explain why your mailing practices earned such a wallop.
Relevant messages have low complaint scores. It’s the single most powerful factor in a good sender reputation, which dictates if your messages reach the inbox and earn a high response. It’s up to marketers and publishers to engage subscribers with every message rather than assume an opt-in gives you license to send whatever you want whenever you want.
Increase relevancy by developing a subscriber-focused content strategy. Address the editorial needs, buying cycles and life stages of your subscribers. New subscribers may welcome more email than long-time subscribers — or the opposite may be true. Tailor messages for subscribers who are up for product or service renewal, have recently purchased, visited a particular section of your website, abandoned their shopping cart, clicked but didn't convert, downloaded a whitepaper, or haven't opened or clicked in the last quarter.
