What about

Helix Sleep

then?

With their average of

27

characters, they're above the limit and should consider to shorten their subject line. Here's one good reason - usuallyy, subject lines that long are not shown entirely on email clients on desktop or mobile. And what's good on saying something that will never be read?

Stay short!

characters, they're right within the sweet spot, which is good! It basically says that you have enough characters to express yourself, but at the same time it will show up entirely on email clients. Just the right amount of characters you want for your own brand!

characters, which is rare - but it means that they have actually more space to express themselves and share their brand values.

Why does this matter? Well, for open rates. Keep it short - on average, you should aim for 16 characters. We consider that above 12 is good, and below 24 is great.

We use Spam Assassin, the main platform used by email providers to score spam. Below 0, you're safe ie. not considered as spam. Below -2, you're great. If you're above 0, you'll likely to be categorized as spam.

So,

Helix Sleep

 gets a score of

-0.4

. What does that mean exactly for their email marketing strategy ?
‍

Well, as stated, it's good! Any score below 0 generally means that the email will not be categorized as spam, especially the ones below -2 - it's a great score, one you want to keep because it helps a lot the deliverability of your emails!

It's good! It means that their email are not headed to the spam folder. However, a score below -2 would be considered even better.

Well, "oops". It's not that good, they're at a level where it could impact their email deliverability.

Does it means they're in the spam folder every time? No. The considered treshhold to be considered spam 100% of the time depends on a lot of factor (generally, consider that a score of 5 means that you end up there every time). Being between 0 and 5 means that it could happen though.
