Automated email sequences are the most powerful component of any email marketing program because they generate revenue continuously without manual effort. A well-designed welcome sequence alone typically drives 3-5x more revenue per subscriber than broadcast campaigns because it catches subscribers at their peak engagement — the first 48 hours after signing up. At Kiwi, we build welcome sequences that introduce your brand, demonstrate value, address common objections, and guide new subscribers toward a first purchase or conversion over a 7-10 day window.
Abandoned cart automation is the single highest-ROI automation for e-commerce businesses. On average, 70% of shoppers abandon their cart before completing a purchase. A three-email abandoned cart sequence — sent at 1 hour, 24 hours, and 72 hours after abandonment — typically recovers 5-15% of those abandoned carts, representing significant revenue with no additional ad spend. Our cart recovery emails combine urgency, social proof, and sometimes a small incentive to bring shoppers back to complete their purchase.
For B2B businesses, lead nurture automation turns cold leads into warm prospects over weeks or months. We build sequences that educate leads about their problem, introduce your solution, provide proof through case studies, address likely objections, and time conversion attempts based on engagement signals. Using tags and conditional logic in platforms like Klaviyo, HubSpot, and Mailchimp, we create dynamic flows where each subscriber's experience adapts based on how they interact with earlier emails — ensuring highly relevant communication regardless of where each lead is in their buyer journey.

An email list is only as valuable as its quality. A list of 5,000 highly engaged, genuinely interested subscribers will outperform a list of 50,000 unengaged contacts acquired through shortcuts. At Kiwi, we build list growth strategies focused on attracting subscribers with genuine interest in your brand — using lead magnets, content upgrades, webinar registrations, free tools, and optimised opt-in forms positioned at high-intent moments throughout your website and marketing funnels.
Lead magnets are the most effective list building tool when matched to your audience's specific needs. A SaaS company might offer a free template or tool. A consultancy might offer a detailed guide or checklist. An e-commerce brand might offer a first-purchase discount code. The key is that the lead magnet provides immediate, tangible value that makes giving an email address feel like an obvious trade. We research what your competitors offer, identify gaps, and design lead magnets that consistently convert at 20-40% of visitors who encounter them.
List hygiene is as important as list growth. Inactive subscribers damage your deliverability by lowering your engagement rates — a key metric ISPs use to decide if your emails go to inbox or spam. We implement re-engagement campaigns for subscribers who have not opened in 90 days, and sunset (unsubscribe) those who do not respond to re-engagement. This keeps your list lean and your deliverability strong, ensuring your emails consistently reach the inbox for your active, engaged subscribers who are actually worth marketing to.

Case Studies — Real Outcomes

full e-commerce build + 5× organic traffic
A premium bag and backpack label came to us with a Shopify theme that converted at 0.6%, paid ads burning through ad spend with no attribution, and zero organic search presence. We rebuilt the storefront on a custom Next.js + headless Shopify stack, redesigned the product pages around a clean editorial layout, shot every SKU in our in-house studio, and shipped 40+ SEO-optimised category and lookbook pages. Within 90 days organic traffic grew 5×, Meta and Google ROAS lifted from 1.4× to 3.2×, and average order value climbed 28% on the back of bundle merchandising and improved size-fit content.

You can have the best email strategy and most compelling copy in the world, but if your emails land in spam, none of it matters. Deliverability is the technical discipline of ensuring your emails reach the inbox, and it is where many email programs fail silently — marketers assume their emails are being read when in reality 20-30% are being filtered to spam. At Kiwi, we audit and fix every technical element of your email infrastructure before launching any campaign.
The key deliverability factors we manage include: sender reputation (monitoring your domain's reputation scores across Sender Score, Google Postmaster Tools, and Microsoft SNDS), email authentication (configuring SPF, DKIM, and DMARC records that verify your emails are legitimately sent from your domain), IP warmup protocols (gradually increasing send volume from new IPs to establish positive sending history), and bounce and complaint rate monitoring (staying below the 2% hard bounce and 0.1% spam complaint thresholds that trigger ISP penalties).
Content and sending practices also affect deliverability. Spam filters are sophisticated machine learning systems that evaluate over 200 signals — from subject line patterns and HTML structure to link domains and image-to-text ratios. We follow inbox-optimised email production standards: clean HTML, appropriate image ratios, clear unsubscribe links, personalised subject lines that avoid spam trigger words, and list segmentation that ensures every email is sent only to subscribers likely to engage with it. The result is consistent inbox placement rates of 95%+ for our managed accounts.
FAQ
We work with Klaviyo, Mailchimp, HubSpot, ActiveCampaign, and Brevo depending on your business type and budget. We recommend Klaviyo for e-commerce and HubSpot or ActiveCampaign for B2B.
Industry averages vary by sector, but a healthy open rate is 25-35%. Well-segmented, permission-based lists regularly achieve 35-45%. Our managed accounts average 32%.
We build list growth strategies using lead magnets, content upgrades, pop-ups, landing pages, and cross-channel promotion to attract highly qualified subscribers at consistent monthly volumes.
Yes, we handle complete platform migrations including subscriber list export/import, template rebuilding, automation recreation, and deliverability warmup on the new platform.
Yes, our email copywriters create all subject lines, preview text, body copy, and CTAs. We develop a brand voice guide and maintain it consistently across every send.
Deliverability rescues are one of the most common requests we get. We audit your sending infrastructure (SPF, DKIM, DMARC), review your list hygiene, analyse your content for spam triggers, and implement a warm-up protocol if your domain reputation has been damaged. Most clients see inbox placement improve from under 70% to above 90% within 45-60 days.
For a simple broadcast campaign to an existing list, we can usually launch within 7-10 business days of onboarding. For full automation builds — welcome series, abandoned cart flows, and post-purchase sequences — expect 3-4 weeks to build, QA, and deploy properly. Rushing automation builds creates gaps that cost you revenue, so we don't cut corners on the setup phase.
There's no hard minimum — we've seen businesses earn strong returns from lists of a few hundred highly engaged contacts. That said, if you're starting from zero, we typically recommend running list-building and lead magnet work for the first 60 days alongside any early send activity, so you're growing your audience while you optimise your messaging.
