On average, the ROI of email marketing is $40 for every dollar spent—almost twice the ROI of SEO, which is $22.24.
But getting subscribers to open your emails isn’t easy.
A research study from Gartner shows 64% of consumers feel overwhelmed by brand communications, which can lead to dwindling open rates.

What are spam filters and why should we avoid them?
Spam filters identify unwanted, unsolicited, and virus-infected emails, and block them from reaching a user’s inbox. These emails are categorized as spam.
Once an email is identified as spam, it’s diverted to the spam folder.
Spam filtering programs come in many forms. Some filters are:
- Content filters: They examine the content of the email and scan for words commonly used in spam emails.
- Blocklist filters: They block emails from senders that have been added to a list of spammers. This list is regularly updated with suspicious email addresses.
- Header filters: The spam filter analyzes the email header to determine the legitimacy of its source. It looks for suspicious information, such as evidence showing that the same email was sent in bulk to preselected recipients.
- Rule-based filters: In this case, the email user sets specific rules that apply to all incoming emails. When an incoming email matches one of the rules, it’s forwarded to the spam folder.
- Language filters: This spam filter blocks incoming emails that are not in the recipient’s native language.
Although these filters help to remove a lot of spam, it’s also easy to see why they can mistakenly flag legitimate emails from ecommerce businesses like yours.
Why are my emails going to spam?
Based on how spam filters work, there are several reasons your emails could be getting flagged as spam, such as:
- Your subject lines are misleading
- You didn’t add an unsubscribe button
- Your ‘from’ data is inconsistent with the content of your emails
- You haven’t properly set up email authentication
- Many of your recipients marked your emails as spam
- Your emails have low engagement rates or high bounce rates
- You’re constantly switching email service providers
You can tackle some of these issues using the best subject lines for emails, and we’ve compiled a comprehensive list.

Best email subject lines for sales: FAQ
1. Should I use emojis in my subject lines?
Emojis can be great for your brand, but they can also seem out of place.
The best question to ask is: do emojis fit into your brand personality?
If they do, then you should definitely use them. If not, A/B test it by adding one emoji in your subject line and monitoring the performance.
2. How long should an email subject line be?
Short subject lines vastly outperform longer ones. In one study, subject lines with just four words had nearly twice as many opens than those with eight words. 7 words and 41 characters is optimal.
If you aren’t sure how long your emails are, use our free Email subject line tester to check your length and character count easily.
3. How to make an attention-grabbing email subject line?
- They are concise (i.e. “Free Shipping TODAY”)
- They ask a question (i.e. “Ready For Black Friday?”)
- They sound urgent (i.e. “50% off sale today only”)
- They start with verbs or numbers (i.e. “Get the latest summer styles”)
- They use personalization (i.e. “Hey [name], ready for Halloween?”]
4. Will the word ‘free’ send my emails to spam?
No.
It’s true that companies sending spammy emails love to use the word ‘free,’ but that doesn’t mean all businesses using the word will wind up in a spam folder. It’s more about how you send emails, and how many subscribers unsubscribe from you (or report you as spam).
Speaking of spam, here’s how to avoid spam filters when sending ecommerce emails to customers.
5. Can I use all caps or exclamation marks?
You can, just sparingly.
Putting a few words in caps is fine, but this should be the exception rather than the rule.
The same thing goes for exclamation marks. Try using just one exclamation mark instead of three to avoid coming off as angry. In most cases, a single mark will convey your message perfectly.
