EMAIL DELIVERABILITY MARKET OVERVIEW

The global email deliverability market stood at USD 1.14 billion in 2024 and is expected to rise to USD 1.24 billion in 2025, maintaining a strong growth trajectory to reach USD 2.38 billion by 2033, with a CAGR of 8.47% from 2025 to 2033.

Deliverability of emails refers to their ability to reach subscribers' inboxes. It is what some marketers use to estimate the likelihood that their email campaigns will arrive in the inboxes of their subscribers, taking into account actual delivery factors like ISPs, throttling, bounces, spam problems, and bulking.

Sending without custom authentication, utilizing a single opt-in, sending from a free domain email address, making it challenging to unsubscribe, employing URL shorteners, and a lack of engagement are all factors that reduce deliverability.

KEY FINDINGS

COVID-19 IMPACT

Utilization of the Application to Fuel Market Growth

The global COVID-19 pandemic has been unprecedented and staggering, with marketing technology experiencing higher-than-anticipated demand across all regions compared to pre-pandemic levels.

For users to get fewer spam emails, many servers have spam filters in place. This feature can prevent email deliverability market growth. Businesses utilize email marketing software to measure and track customer interactions. The program is recognized as a potent communication tool during the COVID-19 outbreak.

LATEST TRENDS

A rise in Rate of Internet Usage to Foster Market Progress

Based on the information the receiving server sends back in the error message, email service providers (ESPs) that handle delivery provide an explanation of why a message was refused (bounced). The email software from Campaign Monitor can precisely measure delivery rates to determine how many emails are received and how many bounce. Bounced emails include those that fail to deliver temporarily because the server is down or fail permanently because the email address is no longer valid. 99% of deliveries are made overall according to Campaign Monitor. Even while we are unable to determine what proportion of emails land in the inbox as opposed to the spam bin, we can draw valid conclusions from metrics analysis.

• According to the Cybersecurity and Infrastructure Security Agency (CISA), over 75% of enterprise email systems in the U.S. implemented AI-based spam detection and deliverability optimization tools by late 2023. These tools improved inbox placement rates by approximately 31%, significantly reducing bounce and spam complaints.

• As per the Messaging, Malware and Mobile Anti-Abuse Working Group (M3AAWG), over 68% of companies adopted DMARC (Domain-based Message Authentication, Reporting & Conformance) policies in 2023, resulting in a 43% drop in spoofed email incidents and enhanced deliverability for verified senders.

DRIVING FACTORS

High Need for Track Rates to Surge Market Progress

The ESP tracks bounce rates, open rates, click-through rates, unsubscribe rates, and spam complaints to give marketers information about how recipients respond to and interact with their emails. Trends in viewer engagement and activity are revealed by tracking these indicators over time. Engagement is crucial to deliverability since it has a direct impact on sender reputation (both for the marketer and the ESP). Excellent email deliverability depends on a strong sender reputation.

Various Features with Changing Technological Trends to Propel Market Growth

The majority of programs offer a free two-week trial period as well as annual payment reductions. The number of features required and how frequently they use email marketing are the main factors influencing costs. This is the case because the majority of software bases its fees on the volume of emails sent or stored in the database. It's essential to keep an eye on operations to see whether monthly costs are going up. Users can email contacts from their database using some CRM software. But it doesn't have all the features that email marketing software does. The CRM's email marketing tool is for users who only occasionally need to send a few emails and don't require a design or automated campaigns.

• The International Telecommunication Union (ITU) reported that 347.3 billion emails were sent daily in 2023, with business email accounting for 65% of total volume. This rise has driven the demand for optimized deliverability solutions to ensure messages reach target inboxes and not spam folders.

• According to the Federal Trade Commission (FTC) guidelines, compliance with CAN-SPAM requirements improved email credibility and delivery rates.

• According to the Internet Engineering Task Force (IETF), over 85% of email traffic globally was flagged as spam in 2023. With ISPs like Google and Microsoft tightening filters, 26% of legitimate marketing emails were still redirected to promotions or spam tabs due to insufficient reputation metrics and lack of feedback loop integration.
