A tale of how hard work (eventually) pays off

By Julia, Deliverability Expert

When we are in a court of law, we are hopefully paying regards to the phrase “innocent until proven guilty.”

Well… when it comes to servers responding to your sending domains and IPs, it is quite the opposite. You must prove your domain to be worthy of delivering to your recipients without an existing precedent… sometimes before you can effectively deliver at all.

Now that the campaigning cycle is coming to another end, this is a great opportunity to work toward preparing your domains and IPs for the most success when the cycle begins picking up again. I think the most important take-away here is: PREPARE your sending domain BEFORE YOU NEED to send with it.

I want to take a few minutes to review how pre-emptively preparing your sending domains can be beneficial to you in months to come.

It takes TIME to scale your domain up to your full sending volume. By getting an early start you are able to avoid rushing the warming process, which could cause you to have blocks and trouble with deliverability.

Even after you’ve scaled to full sending volume, it takes TIME for a server to trust you. Servers are constantly watching how their recipients are engaging with your emails & designated a reputation to your domain/IP based off that response. The only way to continuously improve your reputation, especially on Google and similar servers, is for your audience to be consistently positively engaging with your emails. This means the same users repeatedly engaging with your emails, so sending to only new recipients constantly is actually very poor practice.

And it takes TIME for your audience to recognize and engage with your content. This is a great opportunity to focus less on ads and asks, and more on branding and informational content. It can be extremely valuable to produce very non-controversial content that includes little to no ‘call to actions.’ This type of content generally performs much better in the eyes of the server so it can help you to build your reputation up a bit so you have a buffer when you do want to send more hard-hitting content.

Many of the questions I regularly receive are concerning how quickly we can fully scale a domain & the truth is… there are so many things at play when you are preparing a new domain/IP for sending that the best thing you can do is get a head start. There are very few issues I’ve seen not be able to solved with a little time and persistence.

Goonies Never Say Die when it comes to Spam Traps

By Julia, Deliverability Expert

You’ve heard us mention “spam trap emails” – but do you know what that is?

Spam trap emails can catch even the least spammy of emails. This is because these email addresses are utilized specifically to locate senders who are not closely monitoring their recipient lists.

The thought process behind is that, should one of these “fake” emails enter your recipient list, it would be less likely that you are maintaining your recipient list so well that every email on it is a valid & confirmed subscriber.

Sending emails too many of these “recipients” could lead to many blocks that can be detrimental to your domain reputation and overall deliverability.

So how do you know which emails are spam traps? You don’t. They can be previously active but now expired emails, random emails made by servers for this purpose, and really anything in between. The servers use this method to help protect their users from receiving spam content but it surely adds an extra obstacle to those sending mass emails.

At the very least, you are now aware of what we mean when we say “spam traps” & at the very most, you’ll do your best to keep your email list as healthy as humanly possible.

AND LUCKY FOR YOU… we have a few in-platform tools to help you do just that.

Here are a few pointers to keep in mind regarding your recipient list:

ALWAYS turn on validations when importing new lists, especially large lists that may contain emails you are not personally familiar with…

Be sure to review recipient engagement and behavior – this is made easy with our Automation feature. Creating an engagement series for recipients who have not recently engaged with emails allows us to unsubscribe expired or uninterested recipients and their emails.

Respect the wishes of those who would like to be unsubscribed from your list. This means including visible unsubscribe links in all of our emails & reviewing responses for those who may have intended to unsubscribe. This is not only a legal requirement but will benefit you in the long-run. Angry recipients generally yield more spam complaints…
