Prevent Holiday Email Unsubscribes

Posted on (0 Comments)

It’s that time of year again! Where every night means a different party, the kids remember at 9 PM they signed up to bring 24 cupcakes to class the next day, the list of gifts to be bought is growing, and that holiday ham isn’t going to cook itself. Holidays are amazing, but they undeniably deliver an additional layer of stress that can push people to the edge. By giving your subscribers an option to down-subscribe over the holidays, you can keep them on your list the rest of the year! Our Deliverability Consultant Luke Martinez explains in our latest Webcast Byte

12 Days of Holiday Sending: Watch Your Metrics

Posted on (0 Comments)

On the eighth day of sending, I talked about the importance of listening to what your subscribers want—that low engagement rates and high spam complaints and unsubscribes can be a sign that you need to adjust your content. But how do you find this data and what other metrics should you be looking at? Today, on the tenth day of sending, I’ll break down a few more of these metrics and how you can access them using SendGrid. When talking about engagement metrics, two to really focus on are open and click rates. Opens are an indicator of interest in

We’ve officially made it through to our last topic in our 12 Days of Holiday Sending series and no offense to the first three, but I think we saved the best for last–metrics! I mean how else are you supposed to prove the astonishing success of your email program if you have no stats to back up your claims? So today we’re opening our metrics section by talking about testing. I’m sure you’ve all heard how important testing is, but in the off-chance you haven’t, let me explain.

12 Days of Holiday Sending: Listen To Your Subscribers

Posted on (0 Comments)

For our eighth day of our 12 Days of Holiday Sending series, we’re closing out our “Subscribers” section with a reminder to listen to what your subscribers want. If you’re noticing that your subscribers are not engaging (clicking, opening, sharing, replying) with your emails, or even worse, if you’re seeing lots of unsubscribes or spam complaints, it’s time to take a look at your sending frequency and most importantly, your content. Are your low engagement rates and high unsubscribes telling you that there is a disconnect between what you’re promising your subscribers and what you’re delivering? Do a deep dive

12 Days of Holiday Sending: Who Are Your VIP Recipients?

Posted on (0 Comments)

On our seventh day of 12 Days of Holiday Sending, we’re talking about the loaded question: Who are your VIP recipients? I have a few emails that come to my inbox that I open every single time I see them arrive, without fail, because I can’t wait to read them! Two specifically come to mind: a daily news digest for young professionals, and an email update to a daily deal pop-up shop I stalk. I open the email, I click through, and on a very regular basis (at least for the daily deal site) convert to a sale. For those

The software engineers at SendGrid have been very busy recently, as evidenced by the host of new features that have been added to our market-leading email delivery platform, including improvements to our security, deliverability, and email sending capabilities.

Code Challenge: Adventures in VIM

Posted on (0 Comments)

As developers, we all use different text editors when writing code. This post isn’t meant to say VIM is better than emacs, sublime, etc. VIM is just the editor I switched to a while back, and I wanted to go through some awesome resources that I’ve use to become a better “VIMMER.” For this post, I’m going to walk through some VIM basics that I think the beginner needs. Afterwards, I’ll walk through some great resources. Basics to Get Started The first thing you’re going to notice when you open VIM is that you can’t start writing code. This is
