Email Subject Line Best Practices
We’ve seen some of the best email subject line examples from the internet. It’s time to craft the perfect subject line for your email campaign:
1. Keep it short and simple. Be precise
Almost 77% of emails are read on the phone, so it might get cropped if the subject line is too long. The reader might overlook important information or might be disinterested.
So, you should keep your subject lines within 50 characters so that your followers can read the entire subject. Think about the words which matter the most and exclude unnecessary details.
For example, instead of writing ‘Order No #XXXX is being processed,’ you can write ‘Your order is being processed.’
Also, be precise with your subject lines. For example, use ‘Increase your sales by 60%’ rather than ‘How to increase your sales.’
2. Avoid ‘no-reply’ sender name
A person’s name, like Roger@yourcompany.com, will be more acceptable to an individual than a company name. A familiar name ID gives a feeling that readers are dealing with an actual person rather than an abstract entity.
It is also important never to send emails with a no-reply sender name as they directly go to spam and are usually ignored.
3. Avoid using ALL CAPS
Study shows that 85% of recipients prefer subject lines in lower case. Fully capitalized subject lines look spammy and will be ignored by readers.

Don’t you get the feeling that someone’s screaming at you?
Instead, use simple and engaging language to get your reader’s attention.
4. Segment your lists
It is always better to send emails relevant to your recipients.
That’s why personalization is the way to increase open rates. List Segmentation is a significant aspect of email marketing and will help you send the right content to the right person.

5. Avoid making false promises
Do not make false promises in the subject line and deviate from them in the email body content. This is called clickbait and is usually frowned upon.
Though your subscribers will initially click on these links, they’ll soon lose faith in you.
6. Use numbers and values
A subject line containing numbers will get more attention than vague ones.
Try to add numbers and values wherever possible to attract readers. You can mention the discount value or use numbers to refer to the size of your listicle.

7. Make the recipient feel special
The power of personalization cannot be understated. People want to feel valued.
Choose sentences that instantly grab the recipient’s attention and make them feel special. Here are some great examples:
- “You’re invited!”
- “For our beloved customers only”
- “An exclusive offer for you”
8. Give an engaging pretext
A pretext is not part of the subject line but appears right next to the subject line in the inbox.
It is partly visible to the recipient and has an impact on readability. The preview text shows a bit more on what’s inside. So, to keep it precise and engaging, set the pretext to suit your recipient.
9. User personalization token
Research has shown that marketing emails that included the recipient’s first name in their subject line had higher clickthrough rates.
Including first names in the subject line can be a great start. A dog walking company, Wag!, uses this technique to its advantage by adding the owner’s dog’s name in the subject line.
10. Use questions to get attention
Asking a question in the subject line can be an attention-seeking strategy.
“Are you making these SEO mistakes?”
“Do you know what went wrong with your website?”
These subject lines can be hard to resist as they usually resonate with your audience.
11. Start with action-oriented verbs
Call-to-Action subject lines can prompt readers to take action. For example, while inviting people to a hockey legend dinner, the email subject line can be, “Dine with Bruins legend Bobby Orr.”
