Email marketing is one of the most effective ways to reach potential customers. All successful brands use it to grow their client base and revenue. However, although cold email campaigns are widely used across industries, not every campaign launched is successful.

You can create the perfect content for your email, but users will never going to read it. This happens because sometimes deliverability rates are lower than expected. If you're wondering how to effectively grow cold deliverability rates in real-time, then you need Folderly, which is known as one of the best email deliverability services on the market.

What Is an Email Deliverability and Why Is It Important?

Along with new channels of communication with customers emerging in the world of digital marketing, email remains the most effective way to reach your target audience.

Depending on the strategy, budget, and technical resources, brands send different types of campaigns: monthly newsletters, weekly briefings, regular promotions, etc.

The design also ranges from a simple template with basic blocks to a complex piece of art that uses the latest advances in mail design. 

But no matter how perfect your campaigns are from a visual point of view, you invest your time, effort, and money in them. So, it's very frustrating when they do not reach the addressees due to poor delivery. As a result, you don’t get leads and sales, and your audience misses out on great deals.

To address this issue and avoid similar situations in the future, you need to review your marketing strategy regularly and use Folderly. This email performance solution is based on the best delivery practices. As deliverability provides a visual representation of how many of your emails end up in your subscribers' inboxes, you certainly need this application for your further success.

Reasons Why Your Emails May End Up in Spam

The email may end up in the spam folder for the following reasons:

  • The users manually moved the mail to spam;
  • Individual subscription settings;
  • The mail provider, such as Gmail, rejected the email; or/and
  • The mail server rejected the letter.

The factors that affect deliverability can be divided into internal and external.

Internal factors are the content of the letter and the compliance of the template used with accepted standards. Internal factors include the following:

  • Email subject lines;
  • Email text (content of your email);
  • Email footer.

External factors that can affect deliverability include:

  • The reputation management of the sender;
  • Work with the base of subscribers; and/or
  • Regularity of sending emails.

Why Do You Need To Monitor Deliverability?

You need email deliverability monitoring to: 

  • Win the competition for the attention of users. Having problems with message deliverability, you may miss the chance to offer your solution to the problem. In this case, the user will use the services of competitors.
  • Verify that authentication is set correctly. If the emails reach your audience, then you have received permission from the mail providers, confirming the right to send emails.
  • Confirm the reputation of your service. An automated emailing service is an intermediary between your message and the mail provider. When you send emails, the service provides you with its SMTP server. For your emails to find recipients, they must have a reliable reputation.
  • Understand if something went wrong. Along with the technical side, deliverability is affected by the number of unsubscribers and adding your emails to spam. If the deliverability indicator drops, you should identify the reasons and then make changes to the content of emails and their frequency- improve email deliverability by pulling up other metrics.

What Is Folderly?

Folderly is an AI-based email performance platform for B2C and B2B companies looking to supercharge email marketing. Its main task is to make sure that all client emails get into the Inbox folder and turn mailing lists into an effective marketing tool.

The team deeply studied all the subtleties in marketing, so the processes got maximum efficiency. They divided the work into several main stages, which allowed the team to reach a completely new level. Leads, Cold Email Outreach, Qualification, and Appointment setting consist of additional stages:

1. Mail template writing. Competently writing a mail that will not fall into spam and attract attention is not so easy. To do this, Folderly built a whole department that not only writes the subject and body of the mail but also:

  • Delves into the anatomy of mail and a chain of letters;
  • Maximizes conversion taking into account the experience (when working with clients in different industries);
  • Takes into account the technical side of the sending process- delay, mail limits, spam filters, working CTA.

The clients work in different industries: from outsourcing to companies in the oil and energy industries, factory production, and enterprise systems. There are even those who create components for space rockets for NASA and SpaceX. This allows the team to accumulate experience in B2B lead generation, learn, and grow in almost all industries, maximizing efficiency to help scale the clients' businesses.

2. Deliverability includes sending infrastructure - domain, mailboxes, and their settings. Google forced the team to delve into the third stage in the spring of 2019 after updating the system. Then it became much more difficult to send and deliver letters. There were no tools on the market that adequately help to understand and solve a problem that suddenly arose. At this stage, the team decided to create the product.

How and When Did the Idea to Create the Product First Arise?

Folderly was created out of need. Belkins, as an appointment settings agency, had some mailboxes under its control and did massive email outreach campaigns. Everything went excellent, but then the stats dropped. After a few months, the developers fixed the problem. And during that time, they revised the process of delivering emails. After testing email deliverability, the team concluded that there is a need for a cold email outreach software product like Folderly.

How Does It Work?

As soon as you pay for the subscription, the only thing left for you to do is connect your mailbox and press the "Start Folderly" button. During the day, you will receive the first result on the current domain healths. And you will know exactly how your emails are landing in Gmail, Outlook, and other platforms. After that, Folderly will start to adapt, understand which providers need to be worked on, and will focus on them: send letters, visit, read, and reply. Such an interaction is an imitation of the full-fledged work of a person. Folderly has everything automated to improve and check Sender Score. And you, as a user, will only have to press a couple of buttons. When you upload the body of your email, Folderly highlights all the spam words it contains. Like Grammarly, but for effective mail marketing.

How Does Folderly Help Businesses Make Money from Their Emails?

What do most people think about mail marketing? They imagine they will buy a domain, pay for the mailing service, put up a subscription form, write and layout letters, send them - and everything will be perfect. But as a result, they get an open rate of 1%. So what's the problem?

Everything is focused on three fundamental parts of working with mail:

  • Where did the leads come from and how good are they;
  • What content and with what tools they are sent;
  • How the email infrastructure is configured: domains, DMARC, SPF, DKIM signatures, and so on.

Yes, email marketings needs a comprehensive approach if you want it to last.

And Folderly deals with the last part, the mail infrastructure. It processes a huge array of information: it analyzes the previous activity of the sender and the reputation of the domain and shows what needs to be changed.
