Code Challenge: Learning Swift

Posted on (0 Comments)

Day 1 – Learning Swift As part of the 15-Day Code Challenge that I’ve come up with, I’m learning about 15 new technologies in 15 days. The first is Swift, Apple’s new coding language. I’ve always liked developing for mobile, but I haven’t had the time to explore and play around with Swift until today. In this post I’m going to go over my experience learning Swift and building my first app. For this blog post, I have been primarily reading the ebook that Apple released. It’s a great resource and I highly recommend it for learning Swift.   Step

Content, specifically, is one of the best ways we can scale what we do and the one “C” I would like to push myself further with. So, I’ve decided to take on a challenge of learning 15 new technologies in 15 days and blogging about my experiences with each one. In the upcoming days look out for posts on Android, Google Inbox Markup, AWS Lambda, OpenCV, using Docker and more! You can find the index of my upcoming posts below. As each post is published it will

The SendGrid Ambassador Programme

Posted on (0 Comments)

Over the last year I’ve had the joy and privilege of being in charge of the SendGrid Ambassador Programme for Europe, the Middle East, and Africa (EMEA). My colleague, Yamil, has been in charge of the Ambassador Programme over in the United States and Latin America. If you’ve read my previous blogs, you’ll know by now that one of my absolute favourite parts of this job is teaching. I value teaching higher than anything. I believe if you have knowledge to share, share it. That being said, I jumped at the opportunity in December last year to take on the Ambassador Programme

The following is a guest post by Wesley Yu at Sendwithus. Learn more about Wesley at the bottom of this post. With so many products on the market, keeping customers engaged with your company is getting harder than ever. Customers sign up, they’ll use your product for a while, then they’ll churn. Sometimes churn happens when your company just slips their mind – they forgot about you – other times it happens because they never really experienced the “AH-HA” moment – the moment when your product just clicks and works in their mind. Notification emails bridge that gap. They keep

In support of the release of our CTA Guide (How to Build a Strong Email Call to Action), we’ve been sharing some tips on how to create a CTA strategy. We started by talking about tips around where to place your CTAs (and how many CTAs should you include in an email) and today, we’ll cover the descriptive text in your CTAs. To begin, your CTA should meet two main objectives: CTA Objective #1: Tell the reader what to do. Rely on the main message of your email to showcase the benefit of your offer and leave the role of

Your Holiday Email Questions – Answered!

Posted on (0 Comments)

Our Deliverability Consultant, Luke Martinez, took some time to sit down with me to answer the questions we received during our last webcast Holiday Sending Hacks. The goals of your holiday email can be a bit different than your traditional email program, but the deliverability basics stay the same! Below you’ll find our holiday sending thoughts and recommendations from unengaged users to unsubscribes. What do you consider “unengaged” users? For example, people who don’t open or click in 90 days? Unfortunately, there’s not a specific time we recommend (like X number of days or months of un-engagement), because it really depends on

How Will You Grow Your Email Program in 2015?

Posted on (0 Comments)

As you look to planning for the new year, what does your email strategy look like? If it involves increasing the reach of your email program, you’re in the right place! Growing your mailing list can be pretty complicated. There are plenty of “shortcuts” available to businesses that want to send more email to more people including lists for purchase on the Internet, partners you could potentially share with, services that scrape the internet for email addresses, and more. Unfortunately, those are short-term plays in a long-term game. The key to a successful email program is engagement, and if those
