"30% CTR Gain and Nearly Halving Unsubscribes"
“Before partnering with The Audio Newsletter, our email CTR hovered around 3–4%. After integrating the audio newsletter component, we saw a 30% boost in click-through rates within the first month. We believe the more personal, immersive nature of the audio clips hooked our subscribers enough that they not only opened the emails but actually clicked through to our landing pages.What surprised us most was the drop in unsubscribes—we went from an average unsubscribe rate of 0.9% per send to 0.4% in just two months. Subscribers started telling us they listened in the car or while walking the dog, making our content more ‘sticky’ and convenient.
Beyond CTR improvements, the time spent with our brand skyrocketed. Many recipients reported listening to the full audio segment (often three to five minutes long), compared to skimming our old text newsletter in under 30 seconds.Put simply, The Audio Newsletter gave our marketing a new voice—literally. It set us apart from competitors sending the same stale, text-heavy messages. If you’re looking to stand out in a cluttered inbox, we can’t recommend audio highly enough.”
Proof That Audio Has Helped Others:
1. Trinity Audio: Increases in Time-on-Page & EngagementReference: Trinity Audio has published multiple case studies on their blog and website (e.g., from 2019 onward) highlighting how publishers who add text-to-speech audio players to their articles or newsletters often see improved metrics.Example Metric: One unnamed publisher reported a 27% increase in average time-on-page after implementing audio. Some also reported higher click-through rates on in-audio calls to action—though not always broken out by exact percentages.Relevance: While not a classic “newsletter → audio newsletter” scenario, it does demonstrate that adding audio to originally text-based content can yield measurable engagement benefits (time on page, interactions, and in some cases, CTR on embedded links).
2. SpeechKit: Publisher Case StudiesReference: SpeechKit (a platform that turns written articles into audio) has highlighted several media and publishing companies that adopted audio to capture “multitasking audiences.”Example Metric: One case study mentioned an increase in return visitors by about 20% when audio was added to daily news briefs. Another mentioned an uptick in newsletter signups driven by the novelty of “listen now” features.Relevance: Although the published results tend to focus on engagement, session length, and repeat visits rather than a direct “CTR improvement,” it supports the argument that adding an audio format can stimulate quantifiable audience interaction.
3. Podcast/Audio Marketing ReportsIn the podcast marketing arena (tangentially related to audio newsletters), there are often documented improvements in brand awareness, lead generation, and yes, sometimes CTR on calls to action within show notes or embedded players. While these stats aren’t always 1:1 for “audio newsletter” usage, they reinforce that audio-based formats can drive measurable actions. Example: A HubSpot blog on podcast advertising (2020–2021) noted that 54% of podcast listeners are more likely to consider buying from a brand after hearing an ad on a podcast. While that’s not an explicit “we increased CTR by X%,” it underlines audio’s influence on user actions.
