GMass is shutting down its email warm-up services, and other warm-up tools are following suit. What does this mean for your email outreach? In this article, you’ll find out why most warm-up tools will shut down in the coming months and what you can do next to keep your emails from landing in spam.

Why is GMass shutting down its email warm-up service?

Most warm-up tools, including GMass, use a specific API to offer their services. The providers of this API have decided that GMass and other similar tools might lose access to the API if they don’t shut down their warm-up services.

So, to maintain access to this API, GMass, and other warm-up tools have decided to disable their email warming features.

We saw this coming — here’s why lemwarm will keep working

In August 2022, we changed how our warm-up and deliverability service works by switching from API to an IMAP-based system.

Along with a new and improved algorithm, lemwarm is now one of the best warm-up and deliverability boosters on the market, 100% reliable and safe to use for anyone out there sending cold emails, newsletters, transactional emails, or simply reaching out to an audience via email.

So, how to avoid deliverability issues when sending emails?

If you send emails to an audience, you should check your deliverability before, during, and after sending your campaigns. Only by monitoring your deliverability score, you can prevent your emails from landing in the spam folder.

You can take different actions to increase your deliverability, but keep in mind that only by using an email warm-up and deliverability booster, you can make sure your emails will be received by your audience in their inboxes.

Here are 4 easy steps to start improving your deliverability.

1. Do your technical setup

Your technical setup shows email providers that you are a verified sender and that your emails are safe. This keeps them away from the spam folder.

You can do your technical setup in 5 simple steps:

Step 1: Set up your SPF

SPF stands for Sender Policy Framework. This verifies that your emails have been sent from your domain.

Step 2: Set up your DKIM

DKIM stands for DomainKeys Identified Mail. This guarantees that your emails are not changed after they are sent.

Step 3: Set up your DMARC

DMARC stands for Domain-based Message Authentication, Reporting & Conformance. This helps protect your domain from attacks, phishing emails, etc.

ℹ️  Here's a guide to help set up your SPF, DKIM, DMARC

Step 4: Set up your MX Record

MX Record stands for your ‘mail exchange’ record. This helps providers know what servers accept emails for your domain. Without it, you won’t be able to receive emails.

ℹ️  Here's a guide to help set up your MX Records

Step 5: Set up your Custom Tracking Domain

This allows you to track open and click rates in your emails safely.

2. Keep a healthy mailing list

Having invalid email addresses in your list increases your bounce rate and ruins your sender reputation. Verify your email list regularly, and never send emails to unsubscribed people.

Check out or debounce to make sure you only send emails to valid addresses.

3. Send high-quality emails

Email providers check if your audience is engaging with the emails you send. The only way to get opens and replies is to personalize your emails and always provide value. Here’s how you can make your emails unique and well-structured to stand out in your audience’s inbox.

If you have a large audience, a tool like lemlist can help you send personalized emails at scale and 10x your business growth 🙌

4. Maintain a good sender reputation

A good sender reputation avoids suspicion from email providers and keeps your emails away from spam. Make sure to follow email-sending best practices.

Use these tips while sending emails to avoid landing in the spam folder:

  • send between 50-200 emails per day, per sender
  • spread your sending schedule throughout the day, don’t send them all at once
  • make sure to get at least 1 reply for every 4 emails you send
