Email Deliverability Essentials Six Must Know Tips Internet Marketing

1. It all starts with your subscriber list. Get explicit and high-quality permission.

  • Permission — Make sure you get explicit permission to send e-mail to an address. Also, do not bury permission in your privacy policy. Permission that is assumed just because email addresses were given will often result in high complaint rates and low engagement levels. Also, when a subscriber gives you permission to send him or her e-mails about a specific product or service, they are only agreeing to receive information about that product or service specifically.
  • Set expectations — It is always a good idea to let your subscribers know what they will receive and how often they will receive it. Provide an example on your website of an email so subscribers know what they can expect and the value they will receive.
  • Build your own lists — Do not buy or rent third-party lists or use a list that was derived from some other site with permission specific only to that site. Just because it’s “opt-in” doesn’t mean it’s your opt-in.
  • Don’t pre-check — Instead let the user check the opt-in indicating they want your emails.
  • Confirmed opt-in — Consider a confirm/double opt-in signup process. A confirmation email message requires the subscriber to click on a link to confirm they want to receive your emails. This verifies the subscriber’s email address and their interest in your emails. This helps ensure lower complaints and the ISPs love to hear that you’re doing this when it comes time for a consultant to go to bat on your behalf.
  • Don’t incentivize email sign-ups — The quality of these addresses will likely suffer since a good percentage of people will use a fake address to sign-up just to get your incentive. This will increase invalid rates and complaint rates and could cause serious damage to your sending reputation.
  • Duplicate emails — Remove duplicate addresses from your lists so subscribers don’t get more than one copy of any email.
  • Do not reactivate old subscribers — Many of these old subscribers have probably turned into spam traps. Remove addresses that have not opened a message in the last nine months or longer or that have not been mailed to in the last three months. Put in place a policy to re-engage subscribers that have not opened an email in three to six months, so they will not fall off your list after nine months of inactivity.

2. Create a relationship with your subscribers. Let them know what they’ll receive from you and when they’ll receive it — and then deliver!

  • Provide an example on your website of the emails they will receive from you so the subscriber knows what to expect.
  • Send a welcome letter to your new subscriber no later than three days after they’ve signed up. This is a special message that thanks the subscriber for trusting you with his or her contact information and begins the personal relationship with your company.
  • Create a good impression by engaging right away. Send the first regular email within 10 days of subscribing. Subscribers who start receiving emails earlier are more likely to engage your emails. This interaction also aids in establishing a good email reputation with the ISPs.
  • Maintain a consistent “from” name and email address, preferably your recognizable company name. Brand name recognition is key to reducing complaints. And be sure that name always matches the brand they signed up for.
  • Match the look and feel of the branding and style of the website where they signed up. This provides a comfort level with your mailing that is familiar to your subscribers.
  • Ask them to add your name to their address book. Include a prominent line in your email asking subscribers to add you to their mailbox or safe senders list. This makes you basically “whitelisted” for that subscriber.

3. Be polite when asked to leave. You’ll improve your overall delivery rates!

  • Include a prominently displayed unsubscribe link. Case studies have shown that when there is an unsubscribe link near the top of the page, there are fewer complaints.
  • Honor all unsubscribe requests immediately. A good email software program will do this automatically for subscribers that click on the provided unsubscribe link.
  • Remove invalid emails and spam complaints from your lists immediately. Resending to addresses that have complained or were bounced back as an invalid address sends up a big red flag at ISPs.

4. Beware of inactive subscribers on your mailing list. They may not report you as spam, but they hurt your engagement rates and your delivery.

  • Try to re-engage inactive subscribers with special offers or incentives. Do this regularly when an email address becomes inactive for 60 to 90 days.
  • Try re-permission campaigns. Ask them to reconfirm their subscription before it expires.
  • Be aware that addresses that have been inactive for a very long time may have become invalid or converted to a spam trap.
  • Remove inactive subscribers from your list. Quality is more important than quantity. The importance of removing inactive subscribers from your list can’t be overstated. These subscribers don’t open or click, which drags down your engagement rates, your reputation with ISPs and your delivery. Senders who by halving the size of their mailing list by removing non-engagers, have actually increased deliverability and their revenue.

5. Don’t ignore the nuts and bolts

  • Testing your list, monitoring engagement and creating a readable message are essentials for a successful campaign.
  • Use an inbox monitoring tool or send to your own seeds at the major ISPs before the main campaign is sent. Also, test the actual campaign to see if any delivery problems occurred in live sending.
  • Test rendering – Know what your message really looks like on the various platforms. If your email looks broken, you’ll disappoint your subscribers and erode your brand.
  • Run messages through a spam assassin tool to check content and other factors in your email that may suggest spam to ISPs.
  • Test all links in messages before sending. A link that is not working leaves a bad impression and could prompt your subscriber to unsubscribe or mark your message as spam.
  • Use engagement statistics — high opens, high clicks, and low complaints, to see how “wanted” you message really is. Regularly A/B test to try to determine what really engages your subscribers. Look at campaigns that performed well (high opens/clicks, low complaints) or campaigns that performed badly (low opens/clicks, high complaints) to determine what works for your subscribers.
  • Include a text-only version of the email. If a subscriber can’t receive HTML or is reading your email on a cellphone without HTML capability your message will not be seen.

6. Comply with the CAN-SPAM law

If you are in the U.S., you are legally required to comply with the CAN-SPAM law. However, compliance with CAN-SPAM does not mean your email is guaranteed to be delivered to the inbox — the law still allows ISPs to filter CAN-SPAM compliant email.

  • Include a prominently displayed unsubscribe link in each email that provides a simple method for unsubscribing, preferably a one- or two-click method.
  • Honor all unsubscribe requests within 10 business days, including those received via US postal mail or email.
  • Include a valid postal address and return email address on all messages. P.O. Box addresses are allowed.
  • Provide a valid header (routing) information.
  • Do not use a deceptive subject line.
  • Don’t use false or misleading transmission information.
  • Clearly identify sole sender of the message.
  • Clearly identify the message as an advertisement or solicitation.

By taking to heart these battle-tested principles for creating a successful campaign, you will increase your chances of reaching your subscribers’ inbox. Utilizing these keys and employing a trusted email deliverability company will undoubtedly help to improve your e-mail deliverability rates.
