We may make all kinds of jokes and cheeky references with this assertion, however we’ll lower to the chase: E-mail measurement does matter.
Whereas HTML electronic mail measurement can have an effect on deliverability, the loaded weight of the e-mail (the dimensions of the e-mail as soon as opened, with photos loaded) additionally impacts subscriber engagement. A big electronic mail takes longer to obtain, which may end up in misplaced curiosity and misplaced clicks. What number of instances have you ever been pissed off by an electronic mail picture that takes quite a lot of seconds to load?
So, when a subscriber is ready to obtain an electronic mail, how lengthy ought to she or he wait? What’s an appropriate obtain pace for an electronic mail?
The place We Stand
When growing Marketing campaign Precheck’s picture optimization instrument, we determined to take a stance on what we predict is an appropriate electronic mail obtain pace.
To tell our opinion, we mixed analysis and expertise from our 10 years within the electronic mail advertising and marketing trade. We thought of that infamous eight-second consideration span of the common buyer or reader, in addition to electronic mail analytics on learn/skim charges, and different trade benchmarks from electronic mail groups at MailChimp and Salesforce.
Right here’s the place we landed:
Acceptable E-mail Obtain Speeds
- 3G connection: Lower than 4 seconds
- 4G connection: Lower than 3 seconds
- LTE connection: Lower than 2.5 seconds
- Desktop connection: Lower than 2 seconds
Common Community Information Speeds Throughout the U.S.
When figuring out our optimum obtain speeds, we additionally investigated common community speeds to get a greater sense of what sort of connections customers have within the U.S.
We dug round a couple of sources, together with PCWorld, OpenSignal and Akamai, and calculated common speeds for 3G, 4G and LTE networks. The averages have been primarily based on pattern knowledge from the main cell carriers and the speeds in main metropolitan areas within the U.S. To make clear, a lot of the information is sourced from 2017.
To find out common connection pace for desktop customers within the U.S., we checked out akamai’s 2017 report that confirmed the common connection pace within the U.S. at 18.7 Mbps, a 22% improve over 2016. With that, we estimated 2018’s common pace to take a seat round 22.8Mbps (a 22% improve over 2017).
The Numbers
After operating the numbers, right here’s what we decided as common community knowledge speeds within the U.S. in megabits per second (Mbps):
- 3G: 2.03 Mbps
- 4G: 6.20 Mbps
- LTE: 16.31 Mbps
- Desktop: 22.8 Mbps
These estimates, mixed with our trade information and analysis, helped inform our benchmarks for electronic mail obtain pace.

Clarification: E-mail Measurement and Deliverability
We must always make clear the distinction between electronic mail HTML file measurement and loaded electronic mail measurement. The HTML measurement is all of the code you’ve used to create the e-mail (tables, media queries, and many others.). The loaded weight of the e-mail is how massive the e-mail is as soon as a person opens it within the consumer – this contains all of the downloaded photos.
Spam filters see the dimensions of the e-mail HTML file and don’t take into account the dimensions of any photos within the electronic mail. The pictures are linked to the HTML file, however electronic mail consumer is not going to obtain them till the person opens the e-mail.
