Black Friday is a day of massive volumes for email globally, which puts pressure on every part of the sending infrastructure. All our accounts will be more active than usual, and all ISPs will take longer to deliver emails to the inbox, slowing down the responses.

As you are preparing your Black Friday campaigns, here is a brief summary of all the improvements that we have made in the backend since last year.

We have also prepared a list of best practices for you so that you can make the best of our industry-leading technology.

First and foremost, don't panic! Your success is our success, and we spend a lot of time and effort preparing for this event.

Last year our servers had 100% uptime during the Black Friday weekend and we successfully sent out more than 1.6 billion (yes!) emails, an increase of almost 40% compared to the previous year.

The number of Web Channel impressions has risen by 50% to 16 million. We have increased the number of SMS messages sent by 10% (7.7 million messages sent), and we managed to send out 69 million push messages on Black Friday 2022.

This year we have prepared our systems to an average increase of 30% in the numbers and have carried out a lot of improvements to support this.

For those of you who do not get excited about the technical details, the short version is this: the Automation Center, segmentation, personalization, Web Channel, Interactions, Predict and Analytics, as well as the hardware all these services use have become faster, more reliable and more easily scalable.

For the more tech-savvy readers, here is a detailed (but not exhaustive) list of improvements:

• Scaled up on-premise segmentation machines
• Automation Center reporting service moved to GCP
• Integrations rate limit increased
• Limited the external event payload size
• Optimized pushback mechanism for programs in error
• Auto-failsafe programs with customer-related RD errors

As usual, our worldwide support teams are available 24/7, meaning someone is always there when you need them.

We strive to go above and beyond expectations every single time and our teams are available via email, phone, chat and the usual ticketing system.
