Unsubscribe links and email preference options are not mandatory, but they are strongly recommended and fully supported by MassMailer to help maintain compliance with email regulations and protect sender reputation.

When enabled, MassMailer automatically adds Unsubscribe and Email Preferences links to the footer of your emails. This allows recipients to manage their subscription choices or opt out easily, reducing spam complaints and improving list hygiene. MassMailer also supports subscription groups, so recipients can control the types of emails they receive instead of unsubscribing from everything.

When a recipient’s security system blocks email delivery, it is often due to strict spam filters, firewall rules, or other security measures on their mail server. To improve deliverability:

• Ensure your sending domain is properly authenticated with SPF, DKIM, and DMARC.
• Use a dedicated IP address to maintain a clean sender reputation.
• Monitor bounce codes and feedback loops to identify specific blocking reasons.
• Encourage recipients to whitelist your domain or IP.
• Keep email content compliant with best practices to avoid triggering spam filters.
• Set up feedback loops with Gmail or other providers to receive notifications when emails are marked as spam.

If MassMailer’s delivery rates are very low, it usually indicates deliverability issues rather than a tool failure. Common causes and solutions:

Causes:

• Poor sender reputation or shared IP issues
• Missing or incorrect SPF, DKIM, DMARC setup
• High bounce rates from outdated or invalid email lists.

If you want to proceed with MassMailer, here are the typical steps:

1. Sign up & install:
• Install MassMailer from the Salesforce AppExchange: MassMailer Install
2. Connect to Salesforce:
• Use the guided setup wizard to link your Salesforce org
• Configure sending preferences and permissions
3. Set up email authentication:
• Configure SPF, DKIM, and DMARC for your sending domain
4. Configure templates & lists:
• Create email templates in MassMailer
• Set up dynamic Salesforce lists or campaigns
5. Optional automation & verification:
• Enable email verification for leads/contacts
• Set up workflows or automation for verification and sending
6. Test your emails:
• Send test emails to verify deliverability and tracking
7. Launch campaigns:
• Start sending campaigns and monitor opens, clicks, bounces
• Adjust based on engagement data and feedback loops

It’s safe to send bulk emails (e.g., 20,000 addresses) after you’ve:

1. Verified and cleaned your list with email verification.
   
   
2. Configured SPF, DKIM, and DMARC for your sending domain.
   
   
3. Tested small batches first to monitor bounces and spam placement.
   
   
4. Ensured recipients are segmented and engaged to reduce complaints.

Yes — you can change the “From” email address in MassMailer. MassMailer lets you choose the sender when composing your email in the Outreach Wizard. You can send from:

• the logged‑in user,
• a Common Sender you’ve configured,
• an Organization‑Wide Address, or
• a custom sender using values from your Salesforce fields (e.g., custom email fields).

Here are the key details about the MassMailer subscription plans:

• Basic plan provides a dedicated IP address.
• Pro plan includes Email Monitor and Email Verification features.
• Premier plan includes continuous IP warmup and dynamic templates features.

The MassMailer Onboarding Package is a service that helps new customers set up and configure MassMailer for their Salesforce environment.

Key points:

• Typically includes initial account setup, configuration of email authentication (SPF, DKIM, DMARC), and connecting your Salesforce org.
• Basic user and admin training
• Ensures your account is ready to send emails effectively and maintain deliverability from the start.

To support dedicated IP warming and improve deliverability in MassMailer:

• Start with a low email volume on the new IP to avoid sudden spikes.
• Gradually increase daily sends over 6–8 weeks to build a strong sender reputation.
• Maintain consistent sending patterns and avoid large fluctuations.
• Use MassMailer’s automatic warm-up feature or follow a manual warm-up schedule.

This process helps establish trust with ISPs and improves inbox placement.

Detailed guidance:
Manual warm-up schedule for a new Dedicated IP

No — you should not send large volumes of emails immediately on a new dedicated IP. Doing so can harm your sender reputation and reduce deliverability.

The recommended approach is to gradually increase sending volume over 6–8 weeks during the IP warm-up process. Maintain a consistent, controlled sending pattern to build a strong reputation with ISPs and improve inbox placement.
