SendGrid Spotlights: A Year in Review

TJ quote

“When tasked with a seemingly insurmountable goal, ask yourself ‘how do we get there’ instead of ‘we can’t do it.’” – Isaac Saldana Throughout 2013, we had a number of our SendGrid team members share why they came to SendGrid and what they’ve learned from working at a growing company through our SendGrid Spotlight series. We know that many of our customers and blog readers are entrepreneurs, so to close out the year and kick start another great one, we’d like to highlight some of the inspiration that they’ve shared. Hopefully these insights will inspire you to take 2014 by storm! Isaac Saldana, Co-founder, President “I encourage anyone who is looking to build and grow a start-up to look for

SendGrid Spotlight: Intern Edition

Monica (front in gray tee) and the SendGrid crew.

What It’s Like to Be a Summer Engineering Intern at SendGrid SendGrid’s Intern Program is relatively new… scratch that, very new. This summer was the inaugural season for the 16 interns we proudly introduced into our SendGrid ecosystem. An eclectic bunch (regarding experience) overall—some were just beginning college, while others were right in the middle or recent grads, and others were grad students—but each of them contributed their unique talents and skills towards making this program such a success. Today, we want to take the time to highlight one of our amazing engineering interns, Monica Mishra, on her time here at SendGrid. What attracted you to apply for an internship at SendGrid? Actually I found SendGrid through NCWIT—the National Center

SendGrid Spotlight: Tim Jenkins


As part of our SendGrid Spotlight Series, we’re happy to hear from SendGrid’s co-founder and CTO, Tim Jenkins. I like a challenge. Whether it was breaking the copy protection of Might and Magic as a kid, teaching myself C Programming in high school, elevating to black belt status in Jiu Jitsu, or making email safe from spammers, I need to solve. Luckily, the past four years at SendGrid have been a non-stop journey of coding…and decoding. When I think about what I’ve learned from SendGrid, I look at it from two perspectives. On a granular level, when you’re at a start-up for this long (I’ve worked at a lot of start-ups—none of which lasted more than a year) you learn

SendGrid Spotlight: Jose Lopez

Company, Guest Post

As part of our SendGrid Spotlight Series, we’re happy to hear from SendGrid’s co-founder and web architect, Jose Lopez. It’s been an exciting past few months for the team here at SendGrid. We started off the year by setting big goals for 2013 at our annual kickoff in Mexico and followed that by sending our 100 billionth email. Isaac, Tim, and I are often asked about what it’s like to be a part of such a fast growing company and I think for me, it’s the people that make this company special. So I want to take this opportunity to give a shout out to my teammates here at SendGrid and to share some of the memories I’ve had with

SendGrid Spotlight: Silvia Botros

Company, Guest Post

As part of our SendGrid Spotlight Series, we’re happy to hear from Silvia Botros, SendGrid’s MySQL Database Administrator on the Operations Team. I’ve been a member of the SendGrid family for a year and a half. In that time, the company has doubled in size and has more than tripled its email volume. Needless to say, it’s been quite a ride! I’m often asked what it’s like to be a female engineer and what it’s like to work at SendGrid, so here’s a little background on how the ride has been so far. My Opinion Matters My role at SendGrid is a fun, but challenging one. I’m the primary MySQL DBA on the Ops team based out of our Anaheim

SendGrid Spotlight: Denise Hulce

Company, Guest Post

In our second installment of our “SendGrid Spotlights” series, we are excited to feature Denise Hulce, SendGrid’s VP of Sales and Business Development. The following is a guest post from Denise. The Startup Sprint No cab. No subway. Certainly no bus. Sprinting. That was the only way we were going to make it to a crucial meeting in downtown San Francisco. Sure, it was my very first day with SendGrid, and sure, when I arrived I’d be a sweaty, pulpy mess. But I was not alone. I was running with Isaac, one of the founders of the company. It seems like another era, but it was just three years ago. So the two of us arrived for the meeting, and Isaac

With this achievement, we now send 1% of the world’s non-spam email. When Tim, Jose, and I first started SendGrid, I never imagined that this was possible. It’s humbling

SendGrid Customer Spotlight


Web apps have moved light years beyond their humble beginnings. In the 1990s, business sites resembled little more than electronic bulletin boards and CGI was the standard delivery mechanism.
