What happens if your emails don’t make it to the inbox?

No matter how innovative your design, content, and testing strategies are, they don’t matter if your emails don’t get delivered. So, how can you ensure your emails get delivered? By building and maintaining a solid, positive sender reputation.

Your sender reputation determines whether the email you send is delivered to subscribers’ inboxes, spam folders, or, frankly, at all. Sender reputation essentially refers to how trustworthy your domain(s) and IP addresses (the infrastructure behind your email marketing program) are to spam filters and Internet Service Providers (ISPs). This reputation is determined by a number of factors, including:

  • Sending domain authentication (is your SPF/DKIM/CNAME set up correctly?)
  • The volume of emails being sent from your domain/IP address
  • Positive engagement with your emails (opens, clicks, etc.)
  • Negative engagement with your emails (spam filtering, deletes without opens, complaints)
  • Bounce rates

Remember this: Every email you send can affect your overall reputation in a positive or negative way.

Sender reputation is crucial for delivery—and delivery is essential for a successful email marketing program. So, let’s take a look at what you can do to develop and maintain a positive reputation and best avoid potential email deliverability issues.

Learn what you’re starting with now

If you’re coming to this article truly in the dark about how your domain or IP addresses are performing, start here: Go to Senderscore.org and type in your domain or IP. If your score is high, great! If your score is low, you’ve got work to do.

Build and Manage Your Email List the Right Way

First thing’s first: Build your email list organically. Don’t buy lists.
Now that we have that out of the way, here are some other ways you can maintain your list:

Remove bad email addresses: If you need to, employ double opt-in procedures and bring in list verification/validation services (from Webbula, BriteVerify, Kickbox, or FreshAddress, to name a few)

Monitor and manage spam complaints: Treat these like unsubscribes. Continually mailing to folks who’ve marked you as spam will only make them continue to mark you as spam. And more spam complaints can spell doom to reputation.

Separate “Active” subscribers from “Inactive” subscribers: Treat these subscribers differently. Mail your actives more. Mail your inactives less. If necessary, remove inactives from your list altogether.

Clean your list periodically: If your list is reasonably new, you don’t have to worry as much. But if you have subscribers on your list from 5 years ago, it’s time to make sure those email addresses are still valid. The same folks I mentioned in the bullet above offer list hygiene services.

Send Great Content

Make sure your email content is relevant, mobile-friendly, and code-perfect. If your reputation is borderline, you may want to avoid spammy words and phrases like “guarantee,” “free,” and others. Test frequently and find what works best for your subscribers. There is no “silver bullet” and no “best time to send.”

Maintain Expectations

If you got subscribers to sign up by offering weekly emails, send weekly. If you said you were going to send daily, send daily. Whatever you do, make sure your email send frequency matches the expectations you set at the beginning. A big uptick in frequency (beyond the occasional holiday sale or the like) can spell long-term trouble for programs seeking short-term gain.

Ideally, a solid reputation means you should see this in your metrics:

  • Very low bounce rates
  • Very low complaint and unsubscribe rates
  • Solid open and click-through rates
  • Happy subscribers and great conversion rates for you!

Deliverability is a complex topic, much more complex than one blog post can help you with. That’s why we partnered with our friends and deliverability experts at Inbox Pros for an E-book of The Foundations of Email Marketing Deliverability.

Every email you send affects your deliverability either in a positive or negative way.

There are two general types of emails: Marketing Emails and Transactional Emails: 

1. Marketing emails include “mass” message with the purpose of promoting a product or service. (This is also an important distinction in terms of anti-spam laws.)

2. Transactional emails include purchase confirmation emails, sign-up registration emails with activation links, invoices, password reset emails, shipping confirmation emails, and other notifications.

Your transactional emails should be considered “urgent” and priority #1 in terms of getting into the inbox. The quantity of these messages is generally low (at least on a day-by-day basis), and yet need to be delivered as soon as possible after the transaction is complete.

It doesn’t seem like a big deal, but your marketing emails can seriously affect the possibility of your transactional emails being delivered. Why?

  • Your marketing emails will generally be sent out to a large(r) number of subscribers.
  • Your email server may require a significant amount of time to process and deploy all messages.
  • Marketing messages receive a much higher percentage of spam complaints, blocks, and unsubscribes.

Why would this matter to your transactional messages?

  • Your transactional emails may get delayed by getting stuck behind large marketing message sends.
  • Your transactional emails may get flagged as spam because your marketing messages have received large numbers of complaints.
  • Your marketing message mailing list may be filled with bad email addresses and un-engaged subscribers.

Why do we bring all of this up? Because if you can maintain the infrastructure, you should keep your marketing and transactional emails separate.

How can you separate your marketing emails from key transactional emails?

  1. Use separate IP addresses for your transactional vs commercial email
  2. Use different domain or subdomain names in the “From” and “Reply-to” email addresses.
  3. Send your emails from different servers to prevent blacklisting and throughput issues.

Takeaway:

Separating transactional vs commercial email streams is crucial to ensuring timely delivery of all your important email messages. Achieve this through separate sender and delivery profiles created to manage commercial and mission-critical emails.
