10 best email deliverability tools for reaching the inbox in 2023
Email marketers dream of campaigns with high open rates and lots of engagement. But spam filters, inbox tabs and low-quality email addresses mean the reality is often more of a nightmare. To overcome these challenges, you need an email deliverability tool.
This article will introduce 10 deliverability tools to increase the chances of your messages landing in recipients’ inboxes. They'll help you say goodbye to sending issues and hello to your email marketing dreams coming true.
Why do you need an email deliverability tool?
Email deliverability tools maximize the ROI of your email marketing by helping your emails land in the recipient’s inbox. This is important because an eye-watering 19% of emails go missing or end up in spam. Stopping this from happening will see your bounce rate decrease, open and click rates improve, and spam complaints reduce.
These tools are useful for anyone who does email marketing, whether you have a problem with deliverability or not, as prevention is the best cure for keeping your campaigns in the inbox. But they are also used by people with deliverability problems to get their accounts back in Internet Service Provider's (ISP) good books.
What to look for in email deliverability tool
Email deliverability software has plenty of features to help your messages reach your subscribers. The exact functionality on offer varies between tools, but here are some of the main points to look for.
Email verification scans your email list to check for contacts that you shouldn’t send to. Common problems include non-existent addresses, typos, spam traps, and full inboxes.
Bulk verification lets you check all the email addresses on your list at once, while contact form integration stops people and bots from joining your list with bad addresses in real-time.
Content testing features analyze your emails before you send them and provide content recommendations that increase the chances of your messages being delivered. These tools highlight spam-like words, unusual formatting, email headers, broken links, and the reputation of your sending domain.
Inbox placement features predict whether your email campaigns will land in the inbox of major email platforms like Gmail, Outlook, and Yahoo. They may also highlight whether the message will land in the primary inbox, promotions, or social tab.
Blocklist monitoring features tell you if your domain appears on an email blocklist—lists of low-quality IP addresses or domains that mailbox providers use to filter out spam emails. They also provide steps to help you get off the list.
DMARC monitoring tools protect against unauthorized account usage by tracking your domain in real-time. They alert you if any suspicious activity occurs.
Some of the platforms on our list have extra features that can help with your deliverability in other ways. For example, email sending, interaction reporting, and list health insights.
