Hereโs one thing that companies using HubSpot and marketing automation should consider:
๐๐๐ช๐ฎ๐๐ง๐๐๐ฌ – automated processes to send emails based on CRM data – are wonderful.
BUT – ๐ฐ๐ท๐ฆ๐ณ๐ถ๐ด๐ช๐ฏ๐จ ๐ด๐ฆ๐ฒ๐ถ๐ฆ๐ฏ๐ค๐ฆ๐ด ๐ช๐ฏ ๐ด๐ข๐ญ๐ฆ๐ด ๐ฆ๐ง๐ง๐ฐ๐ณ๐ต๐ด ๐ค๐ข๐ฏ ๐ฉ๐ข๐ท๐ฆ ๐ฅ๐ช๐ณ๐ฆ ๐ค๐ฐ๐ฏ๐ด๐ฆ๐ฒ๐ถ๐ฆ๐ฏ๐ค๐ฆ๐ด.
You likely know the main ones:
Low open rates, high bounce rates, less qualified leads, less opportunities.
But hereโs another one you might not have thought about:
๐๐๐๐ข๐ฆ๐๐ญ๐ข๐ง๐ ๐ฒ๐จ๐ฎ๐ซ ๐๐๐๐๐๐๐๐๐ ๐๐ฆ๐๐ข๐ฅ ๐๐๐ฅ๐ข๐ฏ๐๐ซ๐ฒ ๐ซ๐๐ญ๐๐ฌ!
Let me explain, at least from a HubSpot perspective.
In most organizations, sales teams use sequences, while marketing teams rely on workflows.
The marketing workflows typically handle a lot more data.
Think the thousands of people who go from ads to the website.
These workflows might send dozens of emails, from post-content downloads to post-purchase flows like onboarding.
Not to mention marketing emails like newsletters.
Guess what?
When both sales and marketing send emails from the same domain, everyone is affected.
If sales isnโt following email best practices, like ensuring the recipient’s emails are correct or fit their ICP, that can have a huge impact on marketing.
Yet another reason for sales and marketing to work closer together.
If you havenโt taken a look at how everyone is using email automation at your company, we strongly recommend you start.
