20North is an email marketing agency that delivers expert email list cleaning services for Klaviyo users. Our team helps ecommerce brands improve email deliverability, protect sender reputation, and maximize the ROI of every email campaign. We take the guesswork out of list hygiene and replace it with proven strategies built for sustainable growth.
We identify and remove invalid email addresses from your Klaviyo list before they damage your sender reputation. Our email verification process catches typos, fake emails, and addresses that no longer exist. By eliminating invalid emails, your email marketing campaigns reach real subscribers who can actually engage with your content.
Hard bounces signal to internet service providers that your list contains outdated or incorrect addresses. We monitor your Klaviyo account for hard bounces and remove them promptly to maintain a clean email list. Our hard bounce management keeps your bounce rate low and your deliverability high.
Spam traps can destroy your email deliverability overnight. Our spam trap detection identifies risky email addresses that could land your messages in spam folders or get your domain blacklisted. We use advanced features and real-time email verification to catch these hidden threats before they cause damage.
Not every inactive subscriber should be removed immediately. We build unengaged segments in your Klaviyo account to identify subscribers who have stopped opening or clicking your emails. This segmentation allows us to target these contacts with re-engagement campaigns before deciding whether to keep or remove them from your mailing list.
Duplicate email addresses inflate your active profile count and skew your engagement metrics. We scan your Klaviyo list for duplicates and merge or remove them to give you accurate results. A deduplicated list means more reliable open rates, click-through rates, and better insights into your email marketing efforts.
Role-based emails like info@, support@, and sales@ rarely belong to a single person and often lead to spam complaints. Our email validation process identifies these addresses so you can decide whether to keep them on your subscriber list. Filtering role-based emails improves engagement rates and protects your sender reputation.
Disposable email addresses are temporary inboxes people use to grab a discount code and never engage again. Our email list cleaning service flags these throwaway addresses so you can remove them from your Klaviyo list. Keeping disposable emails off your list protects your deliverability and keeps your subscriber count honest.
We build sunset flows in Klaviyo that systematically identify and remove unengaged profiles over time. Our sunset flow strategy gives inactive subscribers multiple chances to re-engage before removal. This automated approach to regular list cleaning keeps your email list healthy without requiring constant manual effort.
Your sender reputation determines whether your emails reach the inbox or the spam folder. Every time you send to invalid addresses, spam traps, or unengaged contacts, internet service providers take note. A professional email list cleaning service removes these problems before they accumulate and damage your ability to reach customers.
Dirty lists produce misleading data. When your subscriber list includes fake emails, duplicates, and inactive profiles, your open rates and click-through rates don't reflect reality. Email list cleaning gives you accurate results so you can make informed decisions about your email marketing strategy.
A clean list means more of your emails actually arrive where they belong. When you remove invalid emails, hard bounces, and inactive addresses, your deliverability improves across the board. Higher deliverability translates to more opens, more clicks, and better results from every email campaign you send.
Klaviyo pricing is based on your active profile count. Every invalid address, duplicate, and permanently unengaged subscriber costs you money without providing any return. Regular maintenance through list cleaning reduces your active profile count and keeps your Klaviyo bill aligned with the size of your actual engaged audience.
Ready to see how a clean email list can transform your email marketing results? Start with an in-depth list audit. We will analyze your current Klaviyo list, identify problem areas like invalid addresses and inactive subscribers, and build a plan to improve your deliverability and engagement rates.
Increase visibility with SEO that drives qualified traffic to your website and supports your email list growth through organic search. More traffic means more new subscribers entering your Klaviyo flows.
Reach your target audience through paid advertising across Google Ads and social media platforms. Paid traffic fuels your email marketing program with new subscribers while list cleaning keeps that list performing at its best.
We design and develop websites that present your brand with clarity and improve user experience. This includes optimized signup forms, mobile-friendly layouts, and landing pages that grow your email list with valid emails from day one.
Email list cleaning is the process of removing invalid email addresses, hard bounces, spam traps, duplicate contacts, and unengaged subscribers from your mailing list. For Klaviyo users, list cleaning improves deliverability, protects sender reputation, and lowers costs by reducing your active profile count to only engaged, valid contacts.
Most ecommerce brands benefit from regular list cleaning every three to six months, with ongoing monitoring for hard bounces and spam complaints. Brands with high subscriber growth, such as after Black Friday promotions, may need more frequent cleaning. We also recommend running email verification on new subscribers in real time to prevent bad data from entering your list.
The opposite is true. Removing invalid emails and inactive subscribers improves your open rate, click-through rate, and overall engagement metrics. While your total subscriber count may decrease, your email deliverability improves and your campaigns reach people who actually want to hear from you.
A sunset flow is an automated email sequence in Klaviyo that identifies unengaged subscribers and gives them a final opportunity to re-engage before removal. Sunset flows protect your sender reputation by systematically cleaning inactive profiles while giving subscribers a chance to stay on your list if they choose.
We connect directly to your Klaviyo account to analyze your subscriber list, segment unengaged contacts, and implement cleaning strategies. Our process includes email validation to catch invalid addresses, segmentation to identify inactive subscribers, and sunset flow setup for ongoing list hygiene. You receive detailed reporting on what we removed and why.
