Email Marketing

MassMailer allows users to send mass emails beyond Salesforce’s standard platform limits, targeting both standard and custom objects. Additionally, it enables you to schedule and track campaigns for opens, clicks, bounces, unsubscribes, and spam reports. It also offers deliverability features such as email verification and IP support in addition to email authentication, which improves inbox placement.

Mailchimp offers a full-stack email marketing solution with tools for personalization, segmentation, A/B testing, and scheduling. Its behavior-driven automation enables targeted messaging while AI-powered tools help minimize manual efforts by drafting email text and augmenting deliverability.

Analytics

The Email Monitor by MassMailer offers an in-depth insight into sender reputation and deliverability. You can examine domain and IP reputation while verifying compliance with DMARC, SPF, and DKIM protocols. Additionally, you can analyze email contents for spam triggers, set up blacklisting, and preview how an email will be shown to clients. It also provides a predictive deliverability score before sending, so you can spot errors and fix them beforehand.

Attachments

MassMailer enables users to send emails with attachments directly from Salesforce.

It supports dynamic attachments from related objects with a maximum file-size limit of up to 7 MB per email. Additionally, the platform enables you to store files securely within cloud-hosted FTP servers via MassMailer Docs.

Mailchimp does not support direct email attachments. Instead, files are uploaded to Mailchimp’s servers (Content Studio), and a link can be inserted into your email campaigns. Users can share PDFs, images, audio, or documents in the form of a link instead of attaching them directly. Another benefit of Mailchimp is the ability to authorize merge tags and send dynamic file links to individual contacts.

Winner: MassMailer wins as it supports true attachments in addition to dynamic attachments.

Test Emails and Previews

MassMailer enables you to send test emails via its Template Builder or Outreach Wizard. Users can simply fill in sender details, recipient address, and choose whether the test is transactional. Additionally, its built-in ‘Preview Email’ feature allows you to visually assess how the design looks prior to sending.

In its email design, Mailchimp gives you the option to see your campaign on a desktop or a mobile device by choosing ‘Preview Mode.’ From there, you can send a test email with the option ‘Send a Test Email’ enabled and add recipient email addresses. Paid plan can have access to ‘Inbox Preview’ to alter the way an email looks across various clients and devices.
