GMass has been a popular choice for mass emails, and mail merge for a while now. Despite its numerous features, it still has some drawbacks.

Many individuals search for GMass alternatives due to its limited integrations, absence of A/B testing capabilities, and limited customization options.

Additionally, the limited access to automated email sequences and follow-ups, exclusively available in the Premium plan, deters potential users due to its relatively higher cost of $19.95 for individual users and $125 a month for teams.

Luckily, with the evolution of the industry and the emergence of new technologies, several alternatives to GMass are now available on the market. 

In this article, we will share a list of the top five GMass alternatives we thoroughly researched to save you time and effort.

Let's start with our list immediately.

How do I send unlimited emails from Gmail?

Regular Gmail accounts have a daily sending limit of 500 emails. If you want to send unlimited emails from your Gmail account, you can connect it to a third-party SMTP service like SendGrid.

After you sign up for an SMTP service, connect it to your Gmail account utilizing SMTP settings and use Gmail to create your email as usual. The SMTP integration will allow you to send your message to as many recipients as possible.

However, you should remember that sending too many emails in a short time can trigger spam filters and decrease your email deliverability. You should use Skua and its effective email warmup feature to cut down the process and land your messages in recipients' inboxes.
