What is Inbox Scaling?

Inbox scaling means efficiently increasing the volume of emails that you send for cold email marketing purposes. 

The secret to inbox scaling is to use techniques like inbox rotation to manage your email flow effectively and at the same time not exceed the data limits.

For the individual user, this inbox scaling secret will be a pleasant surprise; but for email marketers, it will be a second wind as they handle an unbelievably large volume of messages every day.

These inbox scaling secrets involve applying techniques like inbox rotation. I’ll discuss these secret tricks one by one in the following sections.

Inbox Scaling Secret No 1: Inbox Rotation

The first inbox scaling secret is to rotate your inbox. This is known as inbox rotation. This technique is also known as email rotation or sender rotation.

Using this technique, you can send emails from multiple accounts instead of sending them from a single domain.

Why Should You Know This Inbox Scaling Secret?

If you don’t know this secret technique, your email service provider (ESP) may mark your emails as junk.

Stunned? Let me explain.

Suppose you have a business and need to reach out to your target audience through emails to promote and sell your product or service. 

Here, you’ll need to send hundreds, maybe thousands, of emails every day to a lot of people who don’t know you.

These unsolicited messages to unknown people for sales purposes are called cold emails and the practice of sending them is called a cold email marketing campaign.

Incidentally, this cold email marketing is an email marketing subset.

Now, if you use a single email address to send so many emails every day, your ESP may think you are spamming people and send your emails to the receivers’ junk folders instead of inboxes.

So much waste of time and effort, ain’t it?

The inbox scaling secret technique namely inbox rotation can help you avoid this sorry consequence.

How Inbox Rotation Works

How Inbox Rotation Works

To rotate your inbox, you need to divide your list into small groups, set up new inboxes for each group, warm up those new inboxes and then launch your cold email marketing campaign.

Carve up Your Email List

Divide your target audience into smaller groups so you can dedicate a separate email address for each group.

This will help you create your email content according to the nature of the people you are targeting.

The following tips will help you do this process effectively.

  • Segment your list according to the receivers’ locations, behaviours or interests like ‘possibles’, ‘inactive user’, ‘potential customers’ etc. 
  • Use past data like actions of the receivers, purchase data, response time etc to create meaningful segments.
  • Update your segments periodically according to the behaviour of the receivers. 

Create New Email Accounts

Now set up new email accounts, one for each segment. Follow the steps given below to do it effectively.

This is a key inbox scaling secret to escaping the dreaded junk folder. Read this section carefully, please.

  • Use different ESPs for new email IDs. You can create a Gmail ID for one segment, Yahoo for another and Outlook for the third. This diversification will help you send a lot of emails but at the same time reduce the risk of getting blacklisted if one service provider faces any problem.
  • While creating email IDs, use meaningful addresses that will communicate the nature of your email to the receivers. For example, you can have [email protected] for newsletters and [email protected] for updates.

Warm Up Inboxes

Warming up your inboxes means gradually increasing your email volume. 

If you set up a new account today and start sending 100 emails a day immediately, the service provider may smell a rat and put you under a microscope.

Instead, confine yourself to sending a couple of emails to people you know well. The idea is to get replies from the receivers so the service provider thinks that you aren’t up to bombarding people’s inboxes with unsolicited junk emails.

Be Honest and Polite in Sales Pitch

The basic purpose of a cold email is to extract a response from the receiver. Remember, like you, others also don’t like to be taken for granted.

To avoid being marked as junk by the receivers, do the following.

  • Research your audience thoroughly and send appropriate emails that can address a pain point of the receiver that you target.
  • Be always courteous.
  • Use short subject lines so the receiver can easily understand the purpose of the email.
  • Be honest and to the point. Let the body of the email be creative and catchy.
  • You must sound like an honest businessman trying to help, not to ram something down the receiver’s throat.

Benefits of Inbox Rotation

If properly done, this inbox scaling secret technique will yield several benefits for your cold email campaigns. They are listed below.

It Increases the Sending Volume

The first benefit of inbox rotation is that it helps you send a large volume of cold emails, which a single email address may not allow due to limits set by the service provider.

If you are in the email marketing business, you can easily understand this benefit as you need to send bulk emails every day of the week.

Not only that, rotating your inbox also helps you add new campaigns to the existing one, without campaign duplication. 

This streamlined multi-platform cold emailing is invaluable to your business prospects. 

It Reduces Risk Considerably

Probably the greatest benefit of this inbox scaling secret inbox rotation technique is that it cuts down the risk of being marked as a spammer.

If you don’t send an abnormally high volume of emails every day, inbox rotation will help you send a large volume of emails but won’t scare the service providers into blacklisting you as a spammer. 

It Betters Customer Engagement

Inbox Rotation helps your emails land in the receiver’s inbox rather than the spam folder. This increases the possibility of their being read and responded to. 

This provides you with two benefits. One, you can engage the receiver more and two, it prevents the recipient from marking you as junk immediately. 

Gives You a Backup Option

Inbox rotation yields another important benefit. It provides you with a backup option. 

Even if one of your email accounts gets flagged, you can continue your cold email marketing by using other email addresses. 

This backup option prevents your campaign from getting stopped midway.

Inbox Scaling Secret No 2: Quality Priority

The second inbox scaling secret is to prefer quality over quantity for better cold email deliverability. 

While curating your email list, put the quality of your subscribers before their number. The success of your cold email marketing depends on the quality of your list. 

The reasons for this are listed below.

It Increases Conversions

If you curate your email list based on the quality of your subscribers, the list will contain people who are interested in your offer. They are likely to open your emails, read them and engage.

This increases the possibility of an improved conversion rate and reduces the risk of your emails getting flagged as spam by the ESP.

It Improves Email Deliverability

When your subscribers read your emails more and respond to them, your sender’s reputation with the ESP will considerably improve. 

It will dramatically improve deliverability as most of your emails will land in the receivers’ inboxes instead of spam or junk folders.

This inbox scaling secret of putting quality over quantity increases your email deliverability, which is one of the key objectives of such email campaigns.

It Enhances ROI

Your email marketing campaign involves considerable financial investment and a lot of time. 

By increasing your target audience’s engagement and conversion rate, your loyal subscribers will trigger an enhanced return on investment. 

Inbox Scaling Secret No 3: Authenticate Emails

Always authenticate your emails to build a relationship with your subscribers based on trust and confidence. 

However, authenticating your emails has a few other extra benefits. 

  • Application of authentication protocols like SPF and DKIM to emails helps emails land in inboxes and avoid being flagged as junk or spam. Thus authenticating your emails will increase your email deliverability considerably. 
  • Authenticated emails will promote confidence in the recipients of the legitimacy of your emails. This will build your brand trust and improve your relationships with your subscribers.
  • Emails are a favourite hacking channel for cybercriminals. If you authenticate your emails, it will prevent email spoofing and phishing from acting through your emails.

Inbox Scaling Secret No 4: Cut Out Spammy Language

ESPs nowadays are using technology that considers language used by spammers a major spam metric and flags emails containing such language as junk or spam.

So carefully write your email content. Use simple but effective language and cut out words, phrases and sentences spammers frequently use. Try the following strategies.

  • Avoid terms like ‘free’, ‘only a few items left’, ‘offer ends soon’ etc. These are spammers’ favourite terms and ESPs know it.
  • Keep yourself abreast of terms spammers use and regularly update your email content.
  • Use simple straightforward language to attract and engage your subscribers.
