In 2026, the landscape of email deliverability has become more complex and crucial for businesses aiming to maintain high engagement and revenue. Email warmup, a process essential for establishing a positive sender reputation, plays a pivotal role in ensuring emails land in inboxes rather than spam folders. This article explores the advantages and disadvantages of in-house versus third-party email warmup solutions, providing insights from Formula Inbox, a leader in email deliverability.
What is Email Warmup?
Email warmup is the strategic process of gradually increasing the volume of emails sent from a new or inactive email account to build a positive reputation with Internet Service Providers (ISPs). This process involves generating engagement such as opens, replies, and emails marked as important, which signals to ISPs that the sender is legitimate and trustworthy.
