What Is Email Deliverability?

Email deliverability means the ability of your email to reach your prospect’s inbox instead of winding up in their SPAM folder. Inbox placement can be improved by combining practices such as verifying your prospects’ email addresses, personalizing outreach, and performing email warm-up.

Although email deliverability can never be 100% guaranteed, a professional approach to sending emails can minimize SPAM issues and boost your deliverability. This is what the Growbots deliverability experts can help you with.

Why You Need Email Deliverability Service

Deliverability is one of the critical factors determining the outcome of your email campaigns. Fair enough, since even the top-quality email copies will bring zero results if they end up landing in SPAM folders. Given that, it’s vital to constantly monitor your deliverability and consult experts on improving your deliverability.

How it works

Email deliverability is a complex concept, and, in addition, the factors behind it are constantly evolving, making it impossible to “hack” it completely and make sure you’ll always have 100% deliverability.
Below are factors affecting your deliverability:

your sender reputation – anchored in the correlation between positive interactions with your emails, such as replying to them, and negative interactions, such as getting

your email frequency - not exceeding email service providers' sending limits in the first place

being open about who you are — including your actual contact details in your signature, such as phone number and physical address

your domain age — using a very young domain for sending emails can have an adverse effect on your deliverability

the quality of your mailing list — sending to an outdated list that is likely to contain inactive addresses can trigger deliverability issues

using tracking mechanisms or adding unnecessary HTML content — too much of this can damage your email marketing campaign

However, with the right email deliverability tool, you can effectively monitor your SPAM rates and quickly react to maintain the best deliverability possible.

You can run a deliverability test using online email deliverability solutions, for example, GlockApps, to see your current deliverability. Alternatively, you can turn to MailGenius — this email deliverability software will provide you with additional insights into your online reputation. However, the best option is to monitor your deliverability daily. This becomes possible with Warmbots, which provides real-time SPAM rates and email deliverability statistics.

It depends on your specific case, so the best way would be to consult an expert. Generally, if your SPAM rates are growing, you can take the following steps:

  • pause all your email marketing campaigns
  • connect your emails to an email warm-up tool
  • re-evaluate your email program: copy and signature, your target audience, your domain’s DNS records, and your sending habits
  • clean up your email list

The major benefit of using a professional deliverability service is maintaining the best email deliverability possible. Email deliverability service providers have relevant knowledge and expertise to build a robust email infrastructure and ensure a highly-efficient email program.

Google has recently made an important announcement regarding the ban of automated email warm-up services for Gmail users.

As a result of this decision, all companies that offer outreach or email marketing deliverability services utilizing email warming tools are affected. In order to comply with Google’s terms, Warmbots’ email warming services ceased to be available for Google accounts beginning May 31, 2023.

If you find yourself affected by this change, it’s crucial to explore alternative strategies to ensure optimal transition and continuity of your cold email campaigns. One strategy is to use a cold email warm up tool that is capable of integrating with an IMAP/SMTP inbox and doesn’t require Google’s API access. An example of such a tool is Warmbots.

For more tips on how to maintain high domain reputation and delivery rates of your emails, check out our article where we write about Google’s decision and possible actions that will help you avoid landing in a spam folder.

Moreover, our dedicated deliverability services team, composed of deliverability specialists and email deliverability experts, is prepared to assist you during this transition and answer any questions you might have regarding the change. Simply write to us directly and we will reach out to you.
