On average, emails sent by marketers on Mondays have more errors in their subject lines than do emails sent on other days of the week, according to research from Boomerang. The report was based on an analysis of 250,000 campaigns sent by brands in 2016. The researchers passed the messages through an automated grammar and sentiment checking tool to measure error rates.

The subject line is the first glimpse a recipient gets into the content of the message. Therefore, a successful campaign begins with a captivating subject line -- because with 33% of email recipients reporting that their decision to open an email is based on subject line alone, it's crucial that subject lines offer an element of engagement and inspire the subscriber to learn more.

Speaking about the draft guidance, Chris Combemale, CEO of DMA Group, said: "The ICO has given greater clarity as to when and how consent should be the basis for processing data and highlighted the other 5 legal bases for data processing, including legitimate interest."

"The GDPR gives specific new obligations for organisations, for example around reporting data breaches and transferring data across borders. But the real change for organisations is understanding the new rights for consumers. Consumers and citizens will have stronger rights to be informed about how organisations use their personal data."

There have been multiple experiments surrounding this pattern where users sweep from left to right a couple of times and then downward in an 'F' shape. This is linked to the natural reading flow of our language being in a left-to-right direction. From this we have learned that the left-hand side of an email is actively looked at more than the right-hand side.

Don't confuse the purpose of cold emails and marketing emails. The sole purpose of a cold email is to get a response, most often to start a conversation. But marketers generally don't expect thousands of people to respond to their newsletters -- nor would they want them to -- rather, they just want recipients to click a link and complete some action in their marketing funnel.

No longer is strategy about an immediate conversion from every email. Instead, take a step back to look beyond just massive email deployments. Consider all the different ways your contacts can engage with you --- from email opens and clicks to Web site visits, form submissions and social media -- and what those engagements mean.

"The basic concept of consent, and its main role as one lawful basis (or condition) for processing, is not new. However the GDPR does set a high standard for consent. It builds on the Data Protection Act (DPA) standard of consent in a number of areas, and it contains significantly more detail on both the standard and processes for consent." Jo Pedder, Interim Head of Policy and Engagement.

It's 2017, and we're still stuck with email clients that refuse to accept attachments going north of 25MB. Gmail is changing that. Well, sort of. Google has announced that it is doubling the attachment size for all Gmail users -- going up from 25MB to 50MB. It's a welcome move and should worry rivals Outlook and Yahoo (a lot of people use it!). Except that they don't really need to worry ... yet.

Sending attachments through Gmail is something a lot of us do every day, if not every hour. So it's welcome news that Google has increased the attachment size from 25MB to 50MB. But the new change only works for received mail. If you want to send an attachment, you will still be capped at 25MB. If you want to send any larger files, they will still be transferred via Google Drive.
