1 It’s that time of year again.

2 No, I’m not talking about the summer doldrums or<a>back-to-school</a>prep. I’m not even talking about hurricane season.

3 I’m talking about<a>Black Friday Cyber Monday</a>(BFCM) prep season.

4 You might ask, “Why on Earth would he be talking about that right now?”

5 Because this is the time of year when brands need to get deliverability in order for the big sale, even if it feels early.

6 Here are a few steps you can take now to maximize your deliverability for BFCM:

7 <h2>1. Organize your list now, not in November</h2>

8 There are two key things you can do to avoid potential deliverability woes during BFCM:

9 <ol><li>Make sure your list is up to date.</li>

10 <li>Make sure your list accurately reflects your recipients’ subscription preferences.</li>

11 </ol>If you’ve got systems in place that automatically do that for you, you’re in great shape. But if not, August and September are the right time to conduct a systemic review of that process to make sure it meets your subscribers’ current needs and expectations. Those have a habit of drifting over time as a company grows and your scope expands or shifts.

12 You should delete or consider sunsetting:

13 <ul><li><a>Hard bounces</a></li>

14 <li>Role accounts you don’t need or which aren’t worth sending to, such as sales@fakecompany.com or admin@fakecompany.com</li>

15 <li>Any other kinds of addresses that don’t have a material impact to your bottom line</li>

16 </ul>Sending to these less-qualified recipients might actually be hurting not only your chances of reaching higher-value recipients, but also your<a>domain reputation</a>more than any potential revenue gains would justify.<a>Clean your list</a>accordingly.

17 - Bill Biggers, deliverability strategist at Klaviyo, recommends implementing a<a>sunset flow</a>to re-engage dormant subscribers-typically those who haven’t clicked in the past 12 months. “If they don’t respond, remove them from your active list,” he suggests.

22 Think of this like a credit score. If your domain hasn’t sent a high enough volume of emails that drive the right metrics (like opens and clicks), you’re going to experience increased throttling when your email volume increases (meaning inbox providers hold off on letting your email in). You might also experience<a>soft bounces</a>.

23 And unfortunately, a sudden spike in email volume looks like spammy behavior. You don’t want to scare off inbox providers or make them think you’re sending spam.

24 In the months leading up to BFCM, make sure your content is consistent and easy for your recipients to understand. Big shifts and changes to your branding or overall content could force the algorithms at major inbox providers to re-evaluate your overall reputation, and could potentially cause subscriber confusion.

29 At its core, email deliverability is a 3-way conversation between the sender, the inbox provider, and the recipient. An inbox provider’s main goal is to deliver the emails recipients want to see, while also protecting them from unwanted or harmful messages.

34 Remember, inbox providers reward campaigns and domains that only send email to engaged recipients. If you only segment by demographic data, you miss that part of the conversation entirely.

That means securing copy, images, and any and all assets you need to render your emails well in advance. The biggest BFCM mistakes are usually last-minute pivots in your content strategy driven by gut instinct rather than data.
