Email Monster Pros and Cons

Fastmail Masked Email Pros and Cons

Which Is Cheaper: Email Monster or Fastmail?

Email Monster costs $6.99 per year for its annual plan, or $2.99 per month for monthly billing. Fastmail starts at $6 per month, which comes to $72 per year. That makes Email Monster approximately 90% cheaper. However, it is important to note that these are different categories of products. Fastmail is a complete email hosting platform with 50GB of storage, calendar, and contacts. Email Monster is a focused alias service that works alongside your existing email provider.

If you are happy with Gmail, Outlook, or your current email provider and just want alias protection with newsletter management, Email Monster saves you over $65 per year compared to Fastmail. If you want to move your entire email ecosystem to a privacy focused provider, Fastmail's $72 per year covers everything.

Do I Need to Switch Email Providers for Fastmail Masked Email?

Yes. Fastmail Masked Email is exclusively available as part of the Fastmail email hosting platform. To use masked aliases, you must sign up for a Fastmail account and use Fastmail as your primary email provider. This means migrating your existing emails, contacts, and calendar from Gmail, Outlook, or whatever service you currently use. For many users, this migration process is a significant barrier.

Email Monster requires no provider switch whatsoever. You keep your current Gmail, Outlook, Apple Mail, or any other inbox exactly as it is. Email Monster simply forwards alias emails to your existing address. You can start using it in minutes without changing anything about your current email setup. This makes Email Monster the practical choice for users who are satisfied with their current provider but want to add an alias privacy layer.

Does Fastmail Offer Newsletter Digest Like Email Monster?

No. Fastmail does not bundle newsletters or marketing emails into digests. Every email arrives individually in your Fastmail inbox. Fastmail offers standard email filtering and rules, but there is no digest or bundling feature. Email Monster is the only service that collects newsletters and delivers them as a single weekly or monthly digest email.

The average user receives between 5,000 and 10,000 marketing emails per year. With 46.8% of all email traffic classified as spam, managing this volume is a real challenge. Email Monster's digest feature consolidates these messages into one manageable email per week or per month, saving significant time and reducing inbox clutter.

How Does Fastmail's Password Manager Integration Compare?

Fastmail Masked Email integrates directly with 1Password and Bitwarden. When you sign up for a new service and your password manager detects a signup form, it can automatically generate a new masked Fastmail address. This is a convenient workflow for users who rely on password managers. The alias is created and stored in your password manager alongside the login credentials.

Email Monster does not integrate with password managers, but it offers a simpler workflow. You create aliases on the fly by simply using any address at your namespace. For example, you type amazon@yourname.eml.monster into a signup form, and the alias is automatically created and begins forwarding. There is no need for a separate tool to generate the alias. With email addresses appearing in 53% of all data breaches and the average breach costing $4.44 million, using unique aliases for every service is a smart security practice regardless of which tool you choose.

Why Do Custom Alias Names Matter Over Random Masked Addresses?

Fastmail generates random masked addresses like x7k9m@fastmail.com. These provide privacy but are impossible to identify at a glance. If you have 50 masked addresses, finding which one belongs to which service requires checking your Fastmail settings or password manager. Email Monster lets you create meaningful names like amazon@yourname.eml.monster or netflix@yourname.eml.monster. If spam starts arriving on a specific alias, you instantly know which service leaked your address. Google blocks over 100 million phishing emails daily, but when a legitimate service shares your email, custom alias names make it obvious where the breach originated.
