Why Are So Many People Looking For Mailgun Alternatives And What Are Some Suitable Options?

Why Mailgun users are looking for some cheaper alternatives with free plans.

One of the critical aspects of effective business communication is efficient and reliable email marketing software. Transactional emails are essential to ensure timely response to specific requests, such as password resets, receipts, trial expiration notifications, and invoices. Therefore, using an email sending service with a powerful API, speed, and reliability is indispensable. Mailgun is renowned and widely used by businesses for sending out transactional emails. Mailgun is preferred because it also performs various other functions, such as handling bounced emails, ensuring scheduled delivery, handling complaints, tracking events and emails, etc., efficiently.

Why Mailgun Alternatives?

Mailgun users have been looking for alternative or cheaper email marketing services despite their efficacy and reliability because Mailgun has discontinued its forever-free plan since early 2020.

As per the new plan, users are entitled to 5,000 free emails every month for the initial three months and, after that, need to comply with the pay-as-you-go (PAYG) payment option. The free plan remains suspended. As such, the cheapest plan with all features comes for $35/month with a limit of 50,000 emails. Many customers do not find the new policy satisfactory and are therefore looking for Mailgun alternatives that provide similar features at lower prices.
