Here’s the frequency of emails per company over the two-week period: 

  • Secret Escapes: 13
  • Voyage Prive: 6
  • Expedia: 4
  • Thomas Cook: 3
  • Mr & Mrs Smith: 3
  • Easyjet: 2
  • Skyscanner: 0
  • Ryanair: 0
  • The Weekenders: 0

The Weekenders, Ryanair and Skyscanner are definitely missing an easy trick here. I’m actually inviting them to send me email marketing for heaven’s sake.

Secret Escapes on the other hand are really gunning for my attention with its daily emails. It feels a little much.

These are all fairly generic emails, with the same distributed content that all of its subscribers receive. There’s little personalised to the trips I’ve searched for on the site or enough variation in the subject lines.

How much email is too much email? Marketers need to strike a fine balance between remaining in a recipient’s consciousness and relevant to their customers without overwhelming them or coming across as spam. It’s a difficult line to straddle.

However for travel companies, I would suggest that as holidays are a significant investment and aren’t the most frequent of annual purchases, a daily email definitely becomes part of the general white noise of irrelevance.

That being said, Secret Escapes offers a wide-range of discounted UK based trips that won’t dent budgets significantly. Perhaps it feels like the frequency of emails is justified by offering a variation in price points?

This could certainly be more strategic, with emails specifically capturing the attention of someone who might like a last-minute weekend trip to somewhere a few hours away.

Going back to the point I made earlier about staying at the front of a customer’s mind. Secret Escapes are obviously making this part of its strategy. Filling up inboxes in order to make sure its not drowned out by other marketing emails.

It knows you’re not going to purchase a holiday every day, Secret Escapes is making sure its recipients are always aware that it exists and will likely think of Secret Escapes when they eventually come to booking a holiday.

At what point does a recipient tire of the deluge and hit the ‘unsubscribe’ or ‘spam’ buttons though?

Subject lines

Using some very simple guidelines laid out in the post email subject lines best practice – personalisation, relevance, good length, originality variation and avoiding these 45 words – let’s take a look at some of the best examples from my inbox.

I’ve said before how much I don’t like the use of symbols. Smiley faces, wingdings, hearts, … anything beyond standard text can make a perfectly legitimate newsletter look spam, which is not only off-putting to our eyes but can also trigger spam filters.

However, looking at the entire content of my promotions inbox, it’s clear which email stands out the most…

Travelocity achieved a 10.7% lift in unique opens by using a little airplane in its subject line. It proves that relevancy to content and uniqueness is imperative to proper symbol use.

Other than that, there are a lot of generic deals and offers that don’t exactly scream ‘open’ but here a few that caught my eye because of their variation.

I really like the provocative and attention-grabbing quote used from celebrity guest writer Sue Perkins by Mr & Mrs Smith.

It’s different, funny, stands out from the rest and also shows that Mr & Mrs Smith has a strong editorial voice that means that this won’t be a 100% sales-focussed email.

EasyJet is the only company here to use personalisation using the details I gave during sign-up.

However personalisation means nothing if your data isn’t correct and you don’t have 100% confidence in it, in fact using a person’s name doesn’t really impact the open rate and can come across as needy or begging. Personalisation tends to work best when it’s location or intent based.

Email subject lines are most appealing when they don’t sound like an advert. Words like free, save, % off, don’t miss, sale and hurry are catnip for spam triggers. Try more interesting examples like these:

This is one of the worst examples in my inbox…

A cynical attempt at hijacking the World Cup, which also has absolutely nothing to do with the second half of the subject, which is a generic discount offer.

This is horribly generic and manipulative too. It’s also meaningless.


Finally we get to the content of the emails…

I wrote about Onefinestay’s commitment to strong editorial voice in five evocative examples of ecommerce copywriting, and this is carried over to its emails.

I also like the continuity between the subject line and content, the clear yet subtle call-to-action and the fact that the email solely focuses on this particular location.

This is in direct contrast to Secret Escapes endlessly scrolling emails that deliver offer after unrelated offer in a scattershot affair.

What you’re seeing above is the first of 14 offers in one email.

The only thing that separates Secret Escapes and Voyage Prive’s emails is the name of each company. They pretty much have the same format. Although Voyage Prive has twice as many offers per email.

This is the first of 30 unrelated locations in one email.

At least each one clicks through to a relevant landing page.

Expedia has some of the worst examples here. Getting past the ALL CAPS subject line with the filter-baiting ‘flash sale’, this email shows no examples of offers in the sale, the ‘live’ clock running down to create urgency doesn’t work and finally the email clicks-through to what feels like a fairly generic landing page.

The ‘stop, look, save’ email does exactly the same as above, only this time the content doesn’t really feel particularly relevant to the subject and again it leads to a generic search landing page. There’s nothing enticing, no concrete examples, just meaningless marketing sludge.

EasyJet has a better attempt at trying to find out what new customers might be interested in. It knows I’ve just signed up, hence the nicely inspiring ‘let’s work that passport’. Then I also like the feature below that gives you a handful of holiday types (beach, nightlife, business) with one offer example for each.

This is great as it doesn’t overwhelm the recipient (like Secret Escapes) yet does offer a few concrete examples of offers (unlike Expedia). Also when you click through, it takes you through to a search form with all the relevant details automatically filled in.

I like Mr & Smith’s focus on editorial and strong subject line usage. The only thing it trips on is within the body of the email itself.

This is the top of the ‘Apparently that isn’t the done thing in a five-star hotel’ email I mentioned earlier…

Despite the personalisation, attractive single image and well-written and laid-out copy, there is no reference to the subject whatsoever.

In fact you have to scroll through seven different offers and three screen lengths before you get to the content you were interested in reading.

It’s imperative that your subject lines are relevant to your content and offer immediate gratification when opening. This just feels slyly manipulative.
