A newsletter sent without a clear revenue goal is just noise in someone's inbox. Oddtusk plans, writes, designs, and sends newsletters that give your subscribers a reason to open, click, and buy. Every campaign is mapped to a specific outcome: product launch, sale event, content engagement, or repeat purchase. Every programme connects to our retention marketing and content strategy services.

[ Our working process ]

From content plan to inbox revenue


01

Content Calendar Planning

We map your product launches, sale events, seasonal peaks, and brand moments into a monthly newsletter calendar aligned to your content strategy and performance marketing plan. Each send is assigned a clear revenue goal.
02

Audience Segmentation

Before writing a single word, we define which segment receives each newsletter based on Indian consumer behaviour data. Active buyers, new subscribers, lapsed customers, and VIP purchasers each get tailored versions via our retention CRM.
03

Copywriting and Subject Lines

We write the full newsletter in your brand voice with a focused narrative, a single CTA based on CRO principles, and two to three subject line variants for A/B testing. Preview text is written to complement the subject line and maximise open rate.
04

Design and Template Build

The newsletter is designed inside Klaviyo or Mailchimp, natively integrated with your Shopify store. Mobile-optimised templates are aligned to your brand guidelines with image hierarchy, button placement, and text-to-image ratio set for maximum click-through rate.
05

QA, Scheduling and Send

Before sending, we run a full QA check: link testing, spam score review, mobile and desktop rendering, and send time selection based on your audience's historical GA4 engagement data. A/B test variants split at segment level with a winner send after a defined open window.
06

Reporting and Iteration

Post-send reports in GA4 cover open rate, click rate, conversion rate, attributed revenue, and unsubscribe rate. Subject line winners are logged. Every newsletter makes the next one smarter through a documented optimisation log feeding into the retention programme.

[ Common queries ]

Straight answers to the questions that matter.

The ideal frequency depends on your list size, engagement health, and product activity. For most ecommerce brands we recommend 4 to 8 sends per month. We plan the calendar together based on your goals, and we never recommend sending more than your list can absorb without hurting deliverability.

We handle the full copy. You provide a brief or product direction and we write the newsletter from scratch in your brand voice, following our content strategy framework. If you have existing brand guidelines or copy samples, we use those as references to match your established identity.

We primarily work with Klaviyo and Mailchimp, both of which integrate natively with Shopify and WooCommerce. If you are already on a different platform, we will assess compatibility before onboarding. Platform migration support is available if a switch is warranted.

Yes. We build dynamic segments based on purchase history, engagement level, AOV, and lifecycle stage informed by Indian consumer behaviour data. Different customer groups receive tailored newsletter versions rather than a generic blast, managed through our retention marketing CRM.

We track open rate, click rate, conversion rate, attributed revenue, and unsubscribe rate for every send via GA4. Monthly reports compare performance across campaigns, track subject line test results, and show how newsletter revenue is trending as a share of your total ecommerce marketing contribution.

Yes. Template design is included. We build or adapt a branded template inside your email platform and apply it consistently across all sends. For special campaigns such as product launches or sale events, custom design variations are created following our CRO design principles.

The first newsletter can go live within one week of onboarding. We use the first week to audit your current setup using GA4 data, confirm segmentation, align on brand voice, and build the initial template. From the second week onward, campaigns run on the agreed send calendar without delays.

Yes, and they work best together. Automated lifecycle flows handle moments like cart recovery and post-purchase. Newsletters handle broadcast moments like product launches and sales. Together they ensure your list hears from you consistently as part of a coordinated marketing automation system.

We review the GA4 send data and identify the issue: subject line, send time, content format, segment choice, or CTA placement. Every underperforming campaign is documented with a specific fix applied to the next send, building a compound CRO improvement over time.

Yes. Deliverability monitoring is included. We check domain authentication, suppression lists, bounce rates, and spam complaint rates regularly, with GTM tracking verified to ensure all email events fire correctly into GA4. A clean, engaged list always outperforms a large unmanaged one.
