Email Marketing
The highest return channel your business owns.
Mediasphere's email marketing service plans and writes welcome sequences, newsletters and reactivation campaigns for B2B brands, and reports on revenue per subscriber rather than opens. We start with who is on your list and what they want to hear, give every campaign a number to move before we write it, and you approve every send.
If your list has grown but revenue hasn't, the fix is rarely more sends. It's usually segmentation, sequencing, and a plan for what each contact should hear from you next.
Your email list is one of the most valuable assets your business owns, and most businesses barely use it. Every week without a send is warm interest going cold and a list slowly degrading.
We start by understanding who is on your list, how they got there, and what they actually want to hear from you. From there we build the welcome sequences that turn new subscribers into first time customers, the newsletters that keep your brand on their mind, and the reactivation campaigns that recover the contacts who stopped opening.
Every email marketing campaign carries a number it has to move before we write a word of it. We write everything. You approve it. Your list starts producing returns.
What is included
- Email marketing, campaign planning, and list segmentation
- Welcome and nurture sequences
- Newsletter editorial and writing
- Reactivation and win back campaigns
- A/B testing on subject lines, copy, and offers
- Performance analytics and deliverability monitoring
How we work
- 1List audit and segmentation: we review your existing list health, subscriber sources, engagement patterns, and segmentation. We identify who is active, who has gone quiet, and where the highest value segments sit.
- 2Strategy and sequence design: we map the full email journey including welcome sequences for new subscribers, nurture flows for leads, newsletters for ongoing engagement, and reactivation campaigns for lapsed contacts. Every email has a defined role.
- 3Writing, design, and deployment: we write subject lines and body copy, design email templates, set up automation triggers, and schedule sends. You review and approve before anything goes out.
- 4Testing, deliverability, and reporting: we A/B test subject lines, send times, and content formats. We monitor deliverability metrics (inbox placement, bounce rates, spam complaints) and report monthly on open rates, click-through rates, conversions, and list growth.
Best fit for
- E-commerce and DTC brands sitting on an underused email list where reactivation and retention campaigns can drive immediate revenue
- B2B companies with a long sales cycle that need nurture sequences to keep leads warm between first touch and closed deal
- Any business that has built a list but lacks the in-house time or editorial capability to send consistently and strategically
What this looks like in practice
We took one retailer's promotional email click-through rate from 4.3% to 19.6% across two quarters, without increasing send volume.

We build and manage campaigns in Mailchimp, Klaviyo, HubSpot, ActiveCampaign, or ConvertKit depending on your existing stack. Email design uses each platform's native builder or custom HTML templates when brand standards require it. Deliverability is monitored through platform analytics, Google Postmaster Tools, and sender reputation dashboards. A/B testing runs natively within your ESP. Reporting is delivered through Looker Studio or your platform's built-in analytics, depending on preference.
