1 <p>Considering a migration to Klaviyo before<a>Black Friday Cyber Monday</a>(BFCM)? As the built CRM specifically for B2C businesses, Klaviyo offers unparalleled capabilities for managing your most critical sales period of the year. But timing and implementation are everything when it comes to pre-BFCM migrations.</p>

2 <p>We’ve gathered insights from leading migration experts to answer your most pressing questions about making the switch to Klaviyo before the holiday rush:</p>

3 <ul><li>Shannon Santorineos, VP of customer success, and Tyler Leeth, martech lead at<a>RedVan Workshop</a>, a leading Salesforce, Shopify, and Klaviyo agency with 100% onshore developers.</li>

4 <li>Jamie Smith, director of technical solutions at<a>Anatta</a>, a digital consultancy that precision engineers transformative commerce solutions for enterprise partners</li>

5 <li>Brian Campbell, CEO of<a>CrucialPoint Agency</a>, a retention marketing agency based in Salt Lake City, Utah, operating throughout the U.S.</li>

6 <li>Ben Zettler, CEO of<a>Zettler Digital</a>, a performance marketing agency based in the NYC metropolitan area.</li>

7 </ul><p>Whether you’re worried about deliverability, concerned about downtime, or wondering if you have enough time, this comprehensive FAQ will guide you through every aspect of a successful pre-BFCM migration.</p>

8 <h2>Timeline and planning</h2>

9 <h3>What’s the recommended timeline for completing a full Klaviyo migration before BFCM?</h3>

10 <p>Experts recommend at least a month to complete your migration to Klaviyo.</p>

11 <p>“It’s really going to be unique to each migration,” says Leeth. “No two migrations are the same, but anywhere between 4 and 6 weeks would be a typical timeframe.”</p>

12 <p>Campbell says the length of time needed for a migration depends on list size.</p>

13 <ul><li>Brands with lists under 50,000 subscribers likely need a minimum of 4 weeks.</li>

14 <li>Those with lists between 50,000 and 250,000 need 5-6 weeks.</li>

15 <li>Brands with large lists of 250,000+ should plan for 6-8 weeks.</li>

16 </ul><p><strong>If you get a late start, consider:</strong></p>

17 <ul><li>Working with experienced<a>Klaviyo partner</a></li>

18 <li>Focusing on core functionality only</li>

19 <li>Planning extensive post-BFCM optimization</li>

20 <li>Having detailed fallback plans</li>

21 <li>Keeping your old ESP as backup initially</li>

22 </ul><p>“If brands have a strong partner, there to catch you if you fall, the migration to Klaviyo can go very quickly and smoothly in our experience,” notes Santorineos.</p>

23 <blockquote>If brands have a strong agency partner, there to catch you if you fall, the migration to Klaviyo can go very quickly and smoothly.</blockquote>Shannon Santorineos, VP of customer success<p>RedVan Workshop</p>

24 <h3>What’s the latest we can start migration and still be ready for BFCM?</h3>

25 <p>Experts generally recommend mid-August to mid-September as a good timeframe to get set up in Klaviyo ahead of BFCM.</p>

26 <p>Completing your migration in August gives your brand plenty of time to:</p>

27 <ul><li>Adjust to the new normal.</li>

28 <li>Get used to how things work in Klaviyo.</li>

29 <li>Learn how your processes need to change.</li>

30 <li>Get very comfortable with the new tools before the big weekend.</li>

31 </ul><p>Smith is comfortable with a shorter period: “The latest practical time to start a simple Klaviyo migration is early to mid-September. Starting later than this risks insufficient time for critical deliverability warm-up and testing, especially for larger email lists.”</p>

32 <p>Santorineos adds that<a>IP warming</a>is also critical: “The longer you have, the better.”</p>

33 <p><strong>Migration reminder:</strong>Email takes longer than SMS to migrate. “Because there’s no warming period for SMS, you can start sending to your full list right away,” says Savannah Mazola, SMS digital strategist at Klaviyo.</p>

34 <h3>How do you prioritize migration tasks when working under tight BFCM deadlines?</h3>

35 <p>Of course, every brand is different. Priorities will shift depending on list size, which features and capabilities you’re planning to use, and your marketing goals.</p>

36 <p>Leeth asks brands one guiding question:</p>

37 <p><strong>What are the most critical, revenue-impacting campaigns and segments that are going to get the most attention and have the most impact once they’re migrated?</strong></p>

38 <p>The RedVan Workshop team uses the answer to make their to-do list.</p>

39 <p>At Anatta, Smith uses a “core to enhanced” strategy to prioritize critical tasks like setting up:</p>

40 <ul><li><a>Sign-up forms</a></li>

41 <li><a>Welcome series</a></li>

42 <li><a>Abandoned cart flows</a></li>

43 <li><a>Key segments</a></li>

44 <li><a>Transactional emails</a></li>

45 </ul><p>“Advanced flows, lesser-used segments, and email template redesigns can be optimized after your initial migration,” Smith says. “‘Core-to-enhanced’ ensures you’re functional and revenue-ready first, then optimized.”</p>

46 <blockquote>Advanced flows, lesser-used segments, and email template redesigns can be optimized after your initial migrations. Our approach makes sure you’re functional and revenue-ready first, then optimized.</blockquote>Jamie Smith, director of technical solutions<p>Anatta</p>

47 <h3>Should we migrate all at once or gradually?</h3>

48 <p>Smith recommends a phased “switch by channel” approach for most merchants on Shopify, starting with your most impactful channels, then beginning the migration with critical flows like welcome sequences, then cart abandonment. This method minimizes disruptions and ensures continuous engagement with your subscribers.</p>

49 <h3>What SMS flows should I have live before BFCM?</h3>

50 <ul><li><strong>SMS Welcome Series</strong>(immediate coupon or early access offer).</li>

51 <li><strong>Abandoned Cart</strong>(1 SMS reminders with urgency).</li>

52 <li><strong>Browse Abandonment</strong>(personalized reminder with product link).</li>

53 <li><strong>Post-Purchase Thank You</strong>(tease upcoming BFCM VIP deals).</li>

54 <li><strong>Back-in-Stock Alerts</strong>(great for hot items likely to sell out).</li>

55 <li><strong>Price Drop Alerts</strong>(notify your customers in real time when prices drop significantly)</li>

56 </ul><h3>What are the best SMS campaign types for BFCM?</h3>

57 <ul><li><strong>VIP Early Access</strong>: Text subscribers before anyone else.</li>

58 <li><strong>Doorbuster Announcements</strong>: “Hurry-only 4 hours left to save 50%.”</li>

59 <li><strong>Flash Sales</strong>: Short windows (2-6 hours) to create urgency.</li>

60 <li><strong>Restock Alerts</strong>: “It’s back! Get it before it sells out again.”</li>

61 <li><strong>Cart Recovery Campaigns</strong>: Send a follow-up to those who didn’t purchase.</li>

62 </ul><h3>When should I start sending BFCM-related SMS?</h3>

63 <ul><li><strong>2-3 weeks before</strong>: Build hype with countdowns and grow your list with opt-in promos.</li>

64 <li><strong>1 week before</strong>: Send VIP early access invitations.</li>

65 <li><strong>BFCM weekend</strong>: Send 1-2 SMS per major sale day (morning and evening).</li>

66 <li><strong>Cyber Monday</strong>: Announce last-chance deals.</li>

67 <li><strong>Post-BFCM</strong>: Thank customers + offer extended sale or holiday deals.</li>

68 </ul><h3>What red flags do you look for when assessing whether a brand should attempt a pre-BFCM migration?</h3>

69 <p>Campbell stresses that a migration to Klaviyo won’t fix a company’s problems around branding or acquisition. “Your team needs to be truly ready for migration. Start with a deepdive audit to uncover and fix existing issues, then map out a clear roadmap for the next 3-5 years (or at least the next 12 months). The more you can define your future data needs now, the smoother and more efficient your post-migration period will be,” he says.</p>

70 <blockquote>The more you can define your future data needs now, the smoother and more efficient your post-migration period will be.</blockquote>Brian Campbell, CEO<p>CrucialPoint Agency</p>

71 <p>Smith lists some specific red flags:</p>

72 <ul><li>Understaffed email teams</li>

73 <li>Absence of an internal email manager</li>

74 <li>Poor historical<a>list hygiene</a></li>

75 <li>Inadequate attribution tracking</li>

76 </ul><p>“If Anatta identifies multiple red flags, we advise delaying migration until after the holidays,” Smith says.</p>

77 <p>Leeth takes a look at the big picture and examines the entire tech stack. “If there’s a lot of risk, or stability concerns, we weigh that against how critical BFCM is to the brand.”</p>

78 <h2>Technical concerns</h2>

79 <h3>What are the most common technical hurdles you encounter when migrating ecommerce integrations before BFCM?</h3>

80 <p>Common technical hurdles experts encounter include:</p>

81 <ul><li>Complex integrations with third-party systems</li>

82 <li>Broken sign-up forms</li>

83 <li>Missing custom properties</li>

84 <li>Data overwrites from dual ESP connections</li>

85 </ul><p>“To minimize disruption,” Smith recommends, “follow rigorous QA processes and use parallel testing environments.”</p>

86 <p>Leeth and Santorineos have a QA team that’s well-versed in end-to-end testing as well as the various ways people sign up. “With myriad ways for people to sign up for marketing messaging, subscriber loss is possible,” they say. “We make sure those sign-ups land in Klaviyo.”</p>

87 <p>“QA is where migrations fall apart,” says Zettler. “Every flow, segment, and campaign needs to be tested in a real inbox, not just ‘previewed.’ Check dynamic content, and make sure you don’t have broken links or ‘Hi, first_name.’ Look at mobile and desktop. Every minute spent here saves you days of chaos later.”</p>

88 <blockquote>QA is where migrations fall apart.</blockquote>Ben Zettler, CEO<p>Zettler Digital</p>

89 <h3>How should we approach migrating complex automations/flows, especially welcome series and abandoned cart sequences?</h3>

90 <p>At RedVan Workshop, the team investigates a few core issues ahead of migrating the more complex flows:</p>

91 <ul><li>How is the brand’s<a>CRM strategy</a>working today?</li>

92 <li>What are the challenges their current solution is giving them?</li>

93 <li>What are the brand’s marketing goals moving forward?</li>

94 </ul><p>“The benefit of a migration is that brands get a blank slate mentality,” Leeth says. “We can optimize Klaviyo to overcome the challenges the legacy system gave us.”</p>

95 <blockquote>We can optimize Klaviyo to overcome the challenges the legacy system gave us.</blockquote>Tyler Leeth, martech lead<p>RedVan Workshop</p>

96 <p>“A fresh start is much better than bringing all of your baggage along with you,” Santorineos adds.</p>

97 <p>Smith details their approach: “Anatta maps your existing automation logic into Klaviyo, enhancing it with optimized conditions and targeted segments before publishing. We prioritize welcome and abandoned cart flows and rigorously test to ensure seamless performance and maximize BFCM revenue.”</p>

101 <h3>Will we lose our email history and subscriber data?</h3>

102 <p>The short answer is no.</p>

103 <p>“Klaviyo makes it very easy to get that email history and subscriber data over with the integrations that they have,” says Leeth.</p>

104 <p>“Your subscriber data, including engagement metrics and tags, will be safely migrated to Klaviyo,” Smith agrees. “While historical open and click data may be limited during the transition, Klaviyo predictive analytics quickly bridges this gap, helping you maintain effective targeting and personalization immediately after migration.”</p>

105 <blockquote>Klaviyo predictive analytics bridges the gap, helping you maintain effective personalization immediately after the migration.</blockquote>Jamie Smith, director of technical solutions<p>Anatta</p>

106 <p>Santorineos recommends you don’t wait until the contract for your existing platform is ending, in order “to give yourself a little bit of a buffer.”</p>

110 <p>RedVan Workshop sometimes pauses email automations on the legacy tool and then launches on Klaivyo. “If there were any issues, you could resume in your other system until you’re comfortable launching on Klaviyo,” explains Leeth.</p>

112 <p>“Your sign-up forms will be fine if you follow a well-planned migration process,” Smith says. “Migrating without downtime requires careful auditing and validation of all sign-up forms, including pop-ups, footer forms, and check-out opt-ins. You should also thoroughly test form routing to Klaviyo to ensure no subscriber loss or downtime.”</p>
