Marketing automation promises a great deal, but it doesn’t always deliver.

With the right tools, automating your content workflows can increase conversion rates, lower customer acquisition costs (CAC) and significantly boost the ROI of your marketing strategy.

However, not all automation is equal, and businesses often make mistakes when first turning to automation – mistakes that can be costly to their budget and reputation.

Bad marketing automation can result in a lack of trust in your business, as well as wasted resources and legal issues. A high-profile example is Target’s pregnancy prediction crisis in 2012, in which the brand used purchase data to predict which customers were likely pregnant and send them coupons for baby items – including a teenage girl who hadn’t yet disclosed her pregnancy. This hyper-targeting without proper compliance, safeguarding and human oversight landed Target in legal trouble, damaged their reputation and caused serious concerns over customer privacy. This is just one example of many.

In this article, we’ll explore the 5 common marketing automation mistakes people make and how to avoid them. We’ll also advise you on building your marketing tech stack and personalizing automated marketing messages for maximum impact.

By the end of the article, you’ll learn how to automate your content marketing using a centralized system and unlock higher engagement and conversion rates.

The 5 Common Marketing Automation Mistakes Businesses Make

Too Much Automation, Not Enough Segmentation

One of the most common marketing automation mistakes is a lack of segmentation. It’s important to separate your audience based on behavioral data, as generic messaging can dilute your brand’s value and even erode customer trust.

Using an automation tool like Make.com, you can integrate with Argil and your CRM to create hyper-personalized video content or sales messages for different audience segments. Email segmentation, in particular, can lead to significantly higher conversion rates, and this is often how you reach leads at the middle or bottom of the funnel.

Lack of Personalization

Failing to adapt messages to user intent could be the reason why your conversion rates are low. This is one of the most common marketing automation mistakes businesses make, and it’s easily avoided with the right tools and strategy.

Most people’s inboxes are flooded with missed personalization opportunities – i.e., generic sales emails and discount codes, irrelevant messages, static imagery or boring walls of text. To avoid being relegated to the junk folder, you need to show that your business genuinely understands and can cater to your audience’s needs.

The best way to do this is to use an AI tool like Mailchimp or Semrush to continuously analyze user behavior. The next step is to integrate with a video AI platform like Argil so you can auto-send targeted content when a certain criterion is triggered.

For example, if a customer is browsing a product page on your website but then leaves, you could follow up with a personalized email video message that demos the product and reinforces its value, perhaps even offering a one-time discount.

Branding Inconsistencies

Most businesses operate across multiple channels, and it can be hard to maintain a consistent brand voice – especially when sharing various forms of content.

However, consistent branding is one of the most important pillars of good marketing. When brands use generic chatbots or lose their edge through fragmented, automated messaging, they lose potential customers and damage their reputation.

AI tools can actually help you remain consistent and authentic across platforms. By building brand guidelines into your content tools and using an AI agent like Argil that learns from past data and gets to know your USP, you can ensure your content is on-brand every time.

Overlooking the Power of Video Content

Overlooking the persuasive power of video content is one of the most common marketing automation mistakes businesses make.

Unlike static text and video content, video is a multi-sensory experience and can help to create emotional connections to your audience. With video, you can tell your brand story authentically while boosting your conversion rates with clickable links, branded elements and engaging visual features.

Many SMEs and smaller brands consider video marketing too expensive and time-consuming, but this simply isn’t the case anymore. With Argil, you can create hyper-personalized branded videos in as little as 10 minutes using the most sophisticated AI models and editing features – and for just $39 per month.

It’s also easy to create video variants for different audience segments and personalize your video scripts and visual elements. Our multilingual avatars can also support over 50 different languages and regional accents, so you can create content for a global audience in literally minutes.

Poor Integration

Poorly integrated tools don’t just cause friction and inefficiency for marketing teams – they also create disjointed customer journeys and can lose you valuable leads.

To avoid siloed tech stacks, you should integrate with an automation platform for centralized automation across apps. Tools like Make.com can act as a bridge between marketing tools such as CRMs, email platforms, content platforms (like Argil) and analytics tools to streamline your workflows and create a unified customer view.

Using a centralized platform will help you avoid common marketing automation mistakes like duplicate data entry, poor reporting and out-of-date customer info.

Our hyper-realistic AI avatars can be trained to closely mirror the appearance and speech of you or your brand representative and can perform video scripts with personalized elements.

Because it’s important to maintain a layer of human oversight when setting up automated campaigns, you can also integrate with Slack and other communication tools to send you a notification when your video is ready.

You can then tweak and edit different video elements using Argil’s simple drag-and-drop editing tool, then set up another workflow to automatically trigger an email sequence or schedule a social media post once your video is ready!
