In this competitive landscape of B2C email marketing, the way to go should be how your emails make their way to inboxes and stay off that hated spam folder for maximum engagement and conversion. Spam filters are in place to protect the user from unwanted messages; sometimes they block legitimate marketing communications. Following are effective ways to avoid spam filters and improve deliverability for B2C email marketing.
Use a Recognizable Sender Name and Email Address
The first things recipients notice are the sender name and email address. A recognizable and professional sender name-preferably your brand name-can instill trust and encourage opens. Avoid no-reply email addresses; that just flags to the spam filter that you're not interested in engaging with your subscribers.
Authenticate Your Emails
Email authentication protocols like SPF, DKIM, and DMARC are methods that ensure your emails actually come from you. This will further improve your sender reputation and decrease the chances that your email may be flagged as spam. Consult with your email service provider on how to set these up.
Craft Appealing and Relevant Content

Avoid spammy language. Specific words and phrases, such as "free", "guarantee", and "act now" tend to trigger spam filters. Keep your tone conversational and avoid excessive capitalization and punctuation, like all three exclamation points, or using "100% free".
Value Addition: Let your content also be relevant and of value to the recipients. This will encourage them to engage with you while reducing the chances of recipients reporting your emails as spam.
Use Plain Text Versions Too: Email deliverability could be better if the emails were sent both in HTML and plain text formats. Since some filters prefer plain text, providing both can boost your deliverability odds.

Keep a Clean Email List

Also, consider sending timing, as sending at the right time of day/week when subscribers are most likely to engage may lead to an increase in open rates and a decrease in spam complaints.

Encourage Engagement

Clear Calls-to-Action: When subscribers know clearly what you're asking of them, it's much easier for them to take action. By placing a clear, up-front call-to-action in the text of your email and directing recipients on what to do next, you may see a boost in engagement. It could be to visit your website, complete a survey, or purchase something.
Personalisation: your emails need to be personalised in accordance with each subscriber preference and behavior. For the more relevant your emails will be, the closer recipients will get to opening and engage in them.
- Test and Analyze
Continuously run A/B tests of your emails to find the most engaging subject lines, format of content, and best time of sending. Based on the results of such testing, you can define what works best with your audience and what may have at least some potential to trigger the spam filters. Watch open rates, click-through rates, and un-subscribe rates-test the performance of your email.
