The biggest reservations about email marketing - and why we think they're nonsense

Here, we dispel all prejudices against strategic email marketing once and for all. And, believe us, we’ve heard them all. And refuted them.

Yes, we know. That’s why NOBODY has an email inbox anymore. NOBODY likes emails. That’s nonsense. Email marketing remains one of the most effective marketing strategies with an average ROI of 44 euros for every euro invested. It’s not only alive but constantly evolving and offering innovative ways to engage customers.

BTW: Our approach is omnichannel; with us, you can reach your customers via SMS and WhatsApp, too.

Okay, so they also don’t want shipping notifications from you. No discounts. And of course, no information about new products they can buy before anyone else. In fact, 91 % of consumers in B2C and 73 % of companies in B2B use emails for their communication. With the right strategy and personalized content, we effectively reach your target audience.

Yes, we hear that often. Sure, if you only send one newsletter a month, our prices might not make sense for you. But then you’re not really doing email marketing. Because: Compared to other marketing channels, email marketing is extremely cost-effective. With an ROI of 4,400 % (!), it far exceeds the return of other marketing methods. Try converting that into a CPL for your Meta Ads!

No problem, we have you covered. After all, we not only have over 40 years of combined experience in copywriting, but we’ve also worked in TV, newspapers, and radio for many years. Trust us, there are stories everywhere! This strengthens your brand and keeps you in conversation with your customers.

Only if you don’t know how to do it. You don’t have to deal with the technical implementation; we take care of that. And if you want, we’ll train your team so you can do it yourself later.

Not at all. Thanks to smart segmentation of your contacts, we get to know them better with each email and can address them in an increasingly personalized way. This demonstrably increases open and click rates – and automatically turns one-time buyers into regular customers.

Then we’ll collect some. We analyze your customer base, create meaningful segments, and develop strategies with you to build and maintain your email list. For effective marketing based on a growing data set.

On the contrary, email marketing is one of the most measurable marketing channels. We provide you with regular detailed reports on open rates, click rates, conversions, and ROI, so you can track the success of each campaign precisely.

That’s the best argument for working with rinnstein! We take care of the entire planning, creation, and execution of your email campaigns. So you can focus on your core business.

Consider our fee as an investment in your business. In your company’s growth. Given the high ROI of email marketing (have we mentioned that it’s a whopping 4,400 %?) and our comprehensive support, this investment usually pays off very quickly.

True. We don’t either. But professional email marketing is the opposite of spam. We rely on permission-based marketing where recipients actively agree to receive emails. Our strategies follow strict guidelines, are GDPR-compliant, and deliver valuable content that your customers appreciate.

Is that so? What do you do with all your followers on Instagram? While social media is important, email marketing offers a more direct and personal connection to your customers. With an average open rate of 21.33% compared to an organic reach of about 5.2% on Facebook, emails reach your target audience much more reliably.

That’s great because we perfectly complement your internal team! We bring specialized know-how in email marketing that optimizes and reinforces your existing marketing mix. We work seamlessly and synergistically with your team.

Email marketing is extremely versatile and can be adapted for any industry. We have experience in various industries and develop tailored strategies specifically designed for your industry and target audience.

Then let’s let the numbers speak. Email marketing offers both short-term and long-term benefits. In the short term, we can achieve quick conversions and revenue increases. In the long term, we build strong customer relationships, increase brand loyalty, and create sustainable value for your company.

That’s an invaluable advantage. Because especially with a diverse target audience, email marketing is ideal. Through advanced segmentation and personalization, we target different customer groups with relevant content. For more effectiveness in your marketing.

Let’s talk about it. Previous negative experiences are often the result of lack of strategy or inadequate implementation. We bring proven methods and current best practices to perfect your email marketing efforts and achieve positive results.

Data protection is a central aspect of our work. We are experts in GDPR-compliant email marketing and ensure that all your campaigns comply with current data protection regulations. We take your concern very seriously – and completely off your hands.

We don’t want that either. For us, quality always comes before quantity. We develop a balanced strategy that determines the optimal sending frequency for your target group. Through relevant, valuable content, your emails are perceived by your customers as enrichment and not as a nuisance.

In addition to a „done-with-you“ approach, we also offer you complete handling („done for you“). And when your team then has capacities, we train your employees at a pace that’s manageable for them.

"rinnstein": What's it all about?

“rinnstein”, the gutter, is an emotional metaphor. Yes, it’s meant to be disruptive and to arouse curiosity, but it’s actually based on the experience you have, when everything goes down, and you’d end up “dying somewhere in the gutter”.

Sounds familiar? No plan on what to do next, no feeling for what you really need? Just the urga that something has to completely change to avoid the “gutter death”? Well, that’s where we were back then.

It was all very cynical at the time, but the image of the gutter really helped us to overcome our doubts that we could achieve so much more. Even in the gutter. Especially in the gutter. Because where the water flows, that’s where the energy flows. And where the energy is, that’s where we are.

Everything flowing gathers in this gutter. Creative ideas, effective strategies, disruptive thoughts for unicorns and for long-standing successful projects alike. So when everything is in “flow”, panta rhei, then you too will know what suits you and your company and what maximizes your success. You’ll finally become aware of the gaps in your marketing mix and you will be able to fill them sooner and sooner and for better results.

And now? It’s all about email. 

This highly personalizing tool guarantees an ROI of €44 for every €1 invested. It will help prospects, it will educate fans, it will convert, it builds trust, it’s gonna tell all your stories. 

Put short: It will do everything you want! Oh, you don’t yet know, what you want?

We got you covered! 

The expectations on CLV are high, CPL has to be lowest, just contrary to the AOV – and emails have to hold their own in the mix against all those lead gen channels. (By the way: Did you notice the ROI in email marketing?)

Our email strategies are mainly about retention. You will get to know your customers. (Don’t worry, we’re not on Tinder here!)

It’s time to own your audience. It’s time for trust, for tailored offers, for fans and loyal customers. Our email strategies are anything but banalities or quick fixes. (Okay, if it has to be quick, we could of course get into the ring for you in no time too).

We are both your strategist and your operational partners for you to achieve your goals by email marketing – and that your investment in the gutter pays off.

So: Where does your energy go?
