Consider these subject lines to exude friendliness in your welcome emails:

• Thank you for joining our club
• Welcome to , neighbor
• We’re glad you decided to be here

5. Question type

Use questions in your subject lines to create intrigue and entice your recipients to open your emails.

Questions are great because they urge your subscribers to focus on your subject lines. It prompts them to think of the answers, allowing you to build a deeper connection with them.

Think about what’s important to your subscribers then ask questions referring to it.

For example, if your subscribers are struggling with their email conversion rates, use an email subject line along the lines of, “Were your emails ignored again?”

Because the question you asked is a reality they’re facing, there is a strong connection between their needs and what you’re offering -- making them want to open and read your welcome email.

Example welcome email subject line in question form:

• Curious about our world? Welcome to !
• Are you interested in opportunities?
• Welcome to . Are you ready to step up?
• Ready to know the latest seasonal trends?

Best practices for welcome email subject lines

Follow these welcome email subject line best practices to grab your recipients’ attention and entice them to open your emails.

Practice 1: Use the 4U model

Create compelling welcome email subject lines using the 4U model to move your subscribers along your email marketing funnels.

Implement the 4U model in your subject lines by being:

• Urgent. Encourage your subscribers to open your welcome emails by adding an element of urgency in your subject lines.
• Ultra-specific. Ensure the information in your subject line is consistent with your email content to avoid misleading and potentially losing your subscribers.
• Unique. Come up with unique angles to make your subject lines stand out. This is one of the newsletter best practices that seasoned marketers use to get better results.
• Useful. Show your recipients why they should open your email instantly through your subject lines. Trigger curiosity by giving them a glimpse of the value they get when they open and read your email.

Practice 2: Avoid spam filters and spam traps

Avoid using words that trigger spam filters or get you blacklisted.

The words “100%” and “Free” are classic examples.

Here are some tips for avoiding spam filters and spam traps.

• Learn spam words. Come up with a list of subject line examples then peg your words against a spam word list so you can remove them.
• Don’t use all uppercase letters. Avoid using all caps in your subject lines since they can seem “spammy.” It might trigger spam filters.
• Avoid using too many exclamation points. It’s common practice for spammers to add several exclamation points on their subject lines. Don’t follow their lead by using the same practice; it might cause their ISP to tag your email as spam.

Additional tip: Manage your email list properly to avoid sending emails to those who unsubscribed to your newsletters, or signed up by mistake.

Practice 3: Mention your CTAs on your subject line

Sometimes, the best way to write your subject lines is to mention your calls-to-action. That way, the intent of your email is clear and your recipients know exactly what you want them to do.

This strategy is perfect when you’re giving something of enormous value.

When offering a massive discount, for example, use the email subject line, “Claim Your 70% Discount Now.” The subject line’s message isn’t just clear, but the offer is also catchy.
