Did you know that more than 40% of email campaigns arrive in the recipient’s box with images blocked by default?
Why do images in email arrive blocked?
Find all this in this special post on the topic.
Causes of the problem
The main reason why images in emails are blocked is that of security settings because the malicious content is often sent from a URL. Generally, spammers forward images so that from the opening, they can identify if the forwarding e-mail address exists and also, they get more information such as IP address, location, company name, etc., often misused and harmful to the recipient.
Below is an image that shows what usually happens:
Who makes this block?
Image blocking is controlled by the recipient’s email manager and will depend on which version as it will be displayed to your client. Many companies have additional security features like firewall and antivirus to protect them from these potential attacks. This means that many ISPs block the download of images by security policies, and the email user is the only one who can unlock.
Your Marketing and Design team spends hours working on the images for your email campaign, but how many contacts will actually be able to open the content?
What to do?
1) Be part of your recipient’s contact list
Activate the contact record from the double opt-in, prompting your contacts to add your sender to their contact list; For those already in your base, ask them to add your sender too.
2) Images using the alt tag with CSS
All email providers display alternate text information (ALT text), using appropriate alternate text across all images. Make your email readable even if displayed without images;
<img style=”font-size: 18px; color: white; font-family: Tahoma,Verdana,Arial;” src=”yourimage.jpg” alt=”This is an image” />
3) Use “Bulletproof”
It’s a button made entirely in plain HTML, and inline styles define characteristics like color, texture, and shading.
Its main characteristic is to be visible in most email services, being very interesting to compose call to actions.
<a style=”background-color: #2975c7; border-radius: 4px; color: #ffffff; display: inline-block; font-family: sans-serif; font-size: 13px; font-weight: bold; line-height: 40px; text-align: center; text-decoration: none; width: 200px; -webkit-text-size-adjust: none;” href=”http://”>Button Example</a>
4) Maintain the balance between image and text
Many prefer to use image-based emails to maintain the brand and deliver a beautiful design, but this is not recommended. Image-based e-mails do not take into account cell phone responsiveness, accessibility for the visually impaired, and most spam filters consider the low relationship between text and images as a factor that punctuates an eventual blockage.
