By the time I ate breakfast around 8 a.m. Pacific Standard Time (PST) each day over the Black Friday weekend, Twilio Send Grid had already job title email list processed over a billion emails. mails, calculated according to Eastern Standard Time (EST). Looking at the stats, we handled over 16.5 billion emails from Thanksgiving to Cyber Monday, and over 22.3 billion for the week starting the Tuesday before Thanksgiving. These are very good numbers for the company. From the perspective of an engineering organization, doing this without raising alerts or job title email list degrading the customer experience was incredibly satisfying.

Here, I'll focus on our preparations that made the most critical weekend of the year for our email clients the smoothest yet. How did we make this Black Friday weekend go smoothly?

We had our first 1B day in mid-2016, and we had our first 4B day this Black Friday. That is 400% growth in less than 4 years. To accommodate our ever-increasing scale, to job title email list keep our costs manageable, and to provide greater reliability to our customers, we had to redesign and evolve our mail processing pipeline. Black Friday is coming People ask me, "Why are Black Friday and Cyber Monday so important to you?" This Cyber Monday, we processed 45% more emails than the previous year's peak. Black Friday is one of the biggest retail and spending events in the United States. Traditionally, this is the day when retailers will be in the black (net positive) for the year.
