How to Avoid Email Deliverability Issues During the Holidays

The holiday season is in full swing. Aside from crowded stores and endless checkout lines, the inbox gets particularly busy this time of year, too. In fact, people receive 1.5 times more promotional emails during the holidays than at any other period. This brings all sorts of email deliverability issues that can drag down campaign performance.

As Kevin Senne over at Oracle Marketing Cloud explains, ISPs tend to tighten their grip on incoming mail during the holidays. That’s because mailbox providers slow down the rate of email arrivals to deal with the seasonal deluge. Naturally, this throttling has an effect on both if and when emails reach a recipient’s inbox.

While these email deliverability issues largely bother senders of promotional emails, every marketer who wants to get in touch with prospects or customers during the holidays isn’t immune from these problems.

That’s why we searched the Web for practical tips and best practices to help you avoid holiday-induced deliverability headaches. Let’s take a look at what we learned:

 

  1. Keep your list spotlessly clean

As you’re making your email list, and checking it twice, you might want to have someone recheck it thrice. The first step to your recipients’ inbox starts with the list. Squeaky-clean lists help keep email deliverability issues at bay.

That’s because clean lists tend to give you lower bounce rates, which in turn improve your sender reputation. The better your reputation becomes (in the eyes of ISPs), the better your deliverability gets.

While there’s no shortage of tools and techniques you can use to do some D.I.Y. list cleaning, most sources we dug up strongly recommend working with a third-party data cleaning service provider for best results.

 

  1. Stick to your current sending IP address

If you’re thinking that switching over to a new IP address will give you better deliverability for your holiday campaigns, then you’re in for some very rude awakening. Deliverability expert Return Path cautions against changing your sending IP address, especially during the holiday season.

Using a brand new IP does let you start out with a blank slate, but it’s going to take a while to “warm up” a fresh address and earn the trust of ISPs. Building your sender reputation from scratch isn’t going to happen overnight, and the process will be much longer during the holidays when throttling and stricter spam filters are in place.

 

  1. Watch your mailing frequency

Return Path also warns email marketers not to abruptly increase their sending frequency in the run up to and during the holidays. The biggest mailbox providers keep a close eye on any sudden spikes in send-out rates, slowing down or stopping incoming mails from senders who step on the gas too quickly. In many cases, this can permanently harm sender reputation.

To avoid potential email deliverability issues from sending out too much mail during the holidays, most references we found suggest consistently maintaining your usual email frequency. Other sources also point out that, if you really want to increase your email volume, you need to slowly and gradually increase your frequency over several weeks ahead of the holidays.

 

  1. Wear your authentication badge at all times

Another way to improve deliverability is to use SPF, DKIM, and DMARC authentication. These are tools that tell ISPs you’re someone they can trust. While enabling these items won’t guarantee deliverability (nothing does), they’re a crucial component of building and maintaining a good sender reputation.

As marketing automation provider Real Magnet describes, these three authentication systems allow you to improve your emails’ deliverability and credibility. They implement protocols that verify your domain as the sender, which is something that affects ISPs’ decisions to accept or reject incoming mail.

Enabling all three tools helps guarantee your emails make it into the inbox, as well as protect your emails from spoofing.

 

  1. Focus on the recipient, not the campaign

Google, Yahoo, Hotmail, and other mailbox providers use engagement metrics (opens, clicks, spam reports, unsubscribes, etc.) to determine if your email should end up in the inbox or spam folder.

That’s why avoiding email deliverability issues also means improving how your emails engage your readers. From the subject down to the closing, your email needs actionable copy and compelling design.

We went over some effective tips to write engaging emails in a previous blog entry. Here’s a quick rundown:

  • Use a catchy subject line
  • Make the copy easy to scan and skim
  • Keep it short and strong
  • End with a clear CTA
  • Place main takeaways and CTAs at the top
  • Divide text into sections
  • Use contrasting color schemes
  • Format everything for easy skimming

With these steps, your holiday email campaign will surely minimize, if not avoid, email deliverability issues. From the ContactDB team:
