A great BFCM message only works if it gets delivered. Here's how to get your email, SMS, and push programs prepped for deliverability.

Every BFCM plan rests on one assumption: the message arrives. Deliverability makes that possible so your offers, segments, and creative have a better chance to perform.

And there's new guidance to account for: mailbox providers have formalized sender standards for reaching the inbox, and iOS 26 changed how iPhones treat texts from unsaved numbers. Both reward early preparation.

Here's what to address across email, SMS, and push.

Email: Ramp volume now to protect sender reputation

Email deliverability is your program's ability to reach the inbox instead of the spam folder. Providers evaluate signals including: spam complaints, bounces, engagement, and whether your technical setup proves you are who you claim to be. (New to the fundamentals? Start with our email deliverability guide, then come back for the BFCM specifics.)

Google and Yahoo require bulk senders to authenticate with SPF, DKIM, and DMARC, offer one-click unsubscribe, and maintain spam complaint rates under 0.10% (never exceeding 0.30%). Microsoft now holds high-volume senders to similar standards.

Volume is the other half of reputation. A sudden spike can look suspicious to inbox providers. And it doesn’t support strong ROI either. In 2024 brands that spiked their Q4 sends without a gradual ramp saw 22% lower ROI than all other brands.

How to prepare for BFCM email volume:

• Set your BFCM goal volume using last year's performance and this year's list growth projections.
• Map a ramp schedule that grows sends 5–10% per day, until you reach your target volume. High-volume senders (1M+ emails/day) should hold near 5%; smaller senders (~100K/day) can push 10%.
• Address disengaged subscribers as you ramp. Enroll unengaged subscribers into a sunset or winback flow, and suppress any who remain inactive. A cleaner list raises the engagement signals providers reward.

SMS: Be a name your subscribers' phones recognize

SMS has its own gatekeepers: Programs most comply with applicable law, including the TCPA, and follow CTIA guidelines. On this channel, compliance and carrier trust are what deliverability is made of.

Apple’s iOS 26 adds a layer of complexity for inbox visibility. Apple’s expanded unknown-sender screening routes texts from unrecognized numbers into a separate inbox with no notification. In Attentive data, affected messages saw 30–40% declines in click-through and conversion rates.

How to stay visible on SMS:

• Use Attentive’s patented two-tap™ sign-up unit technology. Because the subscriber sends the first message, it establishes your brand as a known sender.
• Send a contact card in your welcome journey. A contact card is the digital version of a business card: your brand name, logo, and number in a savable file. When a new subscriber saves it, you become a known contact.

Your SMS platform's carrier relationships carry the rest: reliable capacity and priority sending are negotiated long before Cyber Week. Attentive holds a seat on the CTIA board and works directly with carriers—an approach that has produced deliverability satisfaction rates 71% higher than what customers experienced on other platforms.

That reliability is what Attentive SMS is built on. Jewelry brand Kendra Scott counted on it through Cyber Week.

“Attentive was essential in enabling us to connect with our subscribers when it mattered most, providing a reliable platform for timely and targeted engagement that enhanced the Cyber Week shopping experience.”

Push: Protect the permission you earn

Push does not rely on carriers or inbox filtering. Reach depends on whether users grant notification permission—and whether your messages give them a reason to keep it enabled.

That permission deserves care, because on iOS you only get one official chance to ask. Once a user responds to the system's notification prompt, the app can't show it again—someone who taps “Don't Allow” must change the permission manually in their settings.

How to treat the opt-in like the asset it is:

• Protect your one ask with a pre-ask. Before triggering the system prompt, show your own in-app screen explaining what notifications are worth getting—order updates, back-in-stock alerts, early sale access.
• Protect the permission after you earn it. Low-value notifications can increase opt-outs. Save the channel for time-sensitive, high-intent moments—exactly what Cyber Week provides.
• Check your permission health now. Knowing how much of your app audience is reachable by push tells you how many app users you can reach during BFCM, while there's still time to grow it.
