CHALLENGE

Looking For a Solution to Help Customers Improve Email Deliverability

The main goals of Inboxist were:

Help clients boost lead generation and conversions;
Optimize their sales and marketing campaigns.

Like many businesses relying on email outreach, their customers faced common challenges affecting email marketing effectiveness:
Concerns about sender reputation;
Lack of insights into email performance.

Maintaining a high inbox placement is difficult without thorough spam testing, which prompted the Inboxist agency to look for a comprehensive solution to help their customers.

SOLUTION

Making Spam Testing a Standard Email Optimization Practice

To solve these problems, Inboxist chose Inbox Insight from GlockApps, a comprehensive tool for spam testing, domain and IP reputation monitoring, and authentication control that helps to obtain valuable data to optimize email deliverability.

Key reasons Inboxist opted for GlockApps:

Comprehensive reporting for deep insights into email performance;
Scalability for high-volume senders;
Compliance with industry regulations.

Implementation Process:

Inboxist has been using the GlockApps platform for over five years and has fully integrated it into its workflow. The implementation process was easy, allowing the agency to test and optimize its email campaigns before deployment consistently.

Results

How Continuous Deliverability Monitoring Drove Revenue Growth

The adoption of GlockApps brought significant improvements to Inboxist’s operations.

They use GlockApps mainly for:

Inbox placement tests;
Content & HTML suggestions.

For every client they work with, they recommend first sending a test to GlockApps' seed list to verify everything before deployment. This has become a routine practice within Inboxist company as well. It has helped in identifying and removing spammy words, fixing broken links, improving content, and optimizing emails for specific ISPs.

Sender Setup:

Inboxist is an agency that advises clients based on their specific use cases. For example, they recommend a dedicated IP for transactional emails without requiring warm-up or ramp-up. However, for promotional emails, they suggest a dedicated IP only if their sending volume reaches millions per day.

The Inboxist primarily works with the following ESPs:
Klaviyo;
ActiveCampaign;
SendGrid.

Sending Volume: Inboxist’s clients range from sending thousands to millions of emails per day.

IP Setup: They support both dedicated and shared IP customers.

They made it a company-wide standard to run a GlockApps seed test before sending any email campaigns.

One Inboxist eCommerce client experienced a 35% revenue growth due to timely email delivery and improved inbox placement.

Advice to others: “Any company sending more than 10,000 emails per day should use an email deliverability monitoring platform. I recommend GlockApps to stay ahead of deliverability issues and resolve them before they impact your sales.”
