We may make all types of jokes and cheeky references with this assertion, however we’ll minimize to the chase: Electronic mail measurement does matter.
Whereas HTML e 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 photographs loaded) additionally impacts subscriber engagement. A big e mail takes longer to obtain, which can lead to misplaced curiosity and misplaced clicks. What number of occasions have you ever been pissed off by an e mail picture that takes quite a lot of seconds to load?
So, when a subscriber is ready to obtain an e mail, how lengthy ought to she or he wait? What’s an appropriate obtain pace for an e mail?
The place We Stand
When creating Marketing campaign Precheck’s picture optimization software, we determined to take a stance on what we expect is an appropriate e mail obtain pace.
To tell our opinion, we mixed analysis and expertise from our 10 years within the e mail advertising trade. We thought-about that infamous eight-second consideration span of the typical buyer or reader, in addition to e mail analytics on learn/skim charges, and different trade benchmarks from e mail groups at MailChimp and Salesforce.
Right here’s the place we landed:
Acceptable Electronic 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 Knowledge 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 based mostly on pattern information from the key cell carriers and the speeds in main metropolitan areas within the U.S. To make clear, a lot of the info 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 typical connection pace within the U.S. at 18.7 Mbps, a 22% enhance over 2016. With that, we estimated 2018’s common pace to take a seat round 22.8Mbps (a 22% enhance over 2017).
The Numbers
After working the numbers, right here’s what we decided as common community information 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 e mail obtain pace.

Clarification: Electronic mail Dimension and Deliverability
We should always make clear the distinction between e mail HTML file measurement and loaded e mail measurement. The HTML measurement is all of the code you’ve used to create the e-mail (tables, media queries, and so on.). The loaded weight of the e-mail is how giant the e-mail is as soon as a consumer opens it within the consumer – this consists of all of the downloaded photographs.
Spam filters see the dimensions of the e-mail HTML file and don’t think about the dimensions of any photographs within the e mail. The photographs are linked to the HTML file, however e mail consumer is not going to obtain them till the consumer opens the e-mail.
From a deliverability standpoint, we’ve executed some testing round what file measurement triggers spam filters and located that emails bigger than 100KB are inclined to land within the spam folder. It’s additionally a good suggestion to maintain your e mail HTML beneath 102KB to forestall clipping in Gmail purchasers.
To maintain your e mail HTML below the 100KB restrict, think about eradicating redundant or unused types, transferring a number of the content material of the e-mail to a touchdown web page, or eradicating any pointless characters out of your code.
