How can we help?

For Single Lead (email ID) update:

To add the first name to individual leads, you need to navigate to Leads section and then click on 3 dots (…) ellipses.

Click on the Edit lead, provide the first name/last name, and then click Update lead.

For Multiple Leads (Email IDs) update:

To add the First name/Last name to multiple leads, you need to create a column inside the CSV File and then add first name and last name to each of the email addresses.

Then import the CSV file containing the First name/Last name and the Email address with subscription status of the leads.

Finally match the first name/last name column of your CSV file to the first name/last name field and Subscribed with Is Subscribed. Email column is automatically matches with Email address field. Be sure to set Update the lead if lead already exists, “Do you want to import the first line of the CSV file” to No. Then click Import file.

After clicking Import file, lead will be updated as shown below:

To update individual lead information in MailBluster, you need to go Leads section. Then select any lead (email id) by clicking on them.

You can also click on the 3 dots and select Edit lead

You can update information of the selected lead including those custom fields you have defined from Fields earlier

After editing the lead, do click Update lead to save the information.

Importing leads, subscribers, or email addresses to MailBluster is pretty simple. You’ll need a file that supports Comma Separated Values or CSV File format. Make sure your file has two specific columns – for instance, if you have columns labeled “Email” and “Subscribed,” you’ll need to point them to “Email address” and “Is subscribed” before importing them into the Leads section of MailBluster.

In MailBluster, follow these steps to import leads successfully:

1. Just go to Leads > Add new then drag and drop your CSV file.

2. After dropping the CSV file, the following structure of the file will be generated just before import confirmation. Highlight the respective field according to the title of the CSV columns.

3. Scroll down and select these options then click Import file:

Please Note: If your CSV File has the title “First name, Last name, Email, Subscribed” then you need to select “No” for the option “Do you want to import the first line of the CSV file”.

4. Once imported successfully, you will get the results similar to the one shown below:

Here is a sample CSV file on Google Sheets with the mandatory columns highlighted for uploading leads to MailBluster. You can follow this format to upload your data to Leads section of MailBluster.

Please Note: The required columns are Email address and Subscribed.

The CSV File size limit is 10 MB. You cannot upload a CSV file greater than 10 MB.

However, there is a workaround where you can split the CSV file using any third-party apps and then import it to MailBluster Leads.

You can store unlimited number of subscribers/contacts/email IDs/leads under any Brand in MailBluster. Also, there are no hidden cost or fees to store these leads. You can store unlimited leads or email IDs without any charges i.e. completely free of cost.

The following is a screenshare showing leads/email IDs stored in MailBluster Leads section.

To get the total subscriber count of leads, navigate to your Brand > Leads > View All.

Then, under ‘View All‘, select ‘Subscribed‘. You will notice the Total subscriber count (total number of leads who subscribed to your brand) which will be displayed at the bottom right corner as shown below.

To unsubscribe leads in bulk, you need to go to Leads section first, then click on the highlighted checkbox.

After clicking the checkbox, leads on Page 1 will be selected. If you want to select all the leads stored in MailBluster, the click on Select all X leads where X is the total number of leads.

After selecting all the leads, click on Bulk action.

Then click on Unsubscribe.

All the leads will then be set to Unsubscribed status.

To export Leads from MailBluster, you need to go to Leads section, and click Export all.

A popup dialog box will appear showing the email address of the User where the download link will be sent.

Deleting lead individually

To delete a single lead from MailBluster, go to Leads, then select any lead by ticking the checkbox. Then click on the … 3 dots ellipsis then click on Delete lead.

A popup dialog box will appear for confirmation, click Delete and the lead will be deleted instantly.

Delete selected leads in bulk

To delete selected leads in Bulk from MailBluster, go to Leads, then select leads by ticking the checkbox.

Then click on the Bulk action. Click on Delete leads.

A popup dialog box will appear for confirmation, click Delete and the selected leads will be deleted instantly.

MailBluster does not allow duplicate leads. If a duplicate lead is found, any existing lead information will be updated with the new details or skipped based on the preferences.

If you want to update the existing leads of your brand from Google Sheets, the best way is to import them to your brand. To do so:
1. Download the Sheet as CSV. MailBluster only supports CSV format.
2. Upload it from Leads > Add new > Import leads page.
3. Make sure to enable Update existing leads, otherwise MailBluster will skip importing existing leads.
4. Finally, Import.

Another approach is to use 3rd party applications like Make or Integrately. You can instruct them to read your Google Sheets file and create/update MailBluster leads from it.

Please note: These are 3rd party apps and may charge you for using it.

The last approach requires programming knowledge. Here you need to read the Google Sheets file programmatically and call using MailBluster developer API to update the lead.

MailBluster does not allow sending emails to purchased lists, and we highly discourage it if anyone tries to upload or import purchased lists from 3rd parties in MailBluster. You can send marketing emails to subscribed lists and legally collected leads, but you should not send them to purchased lists. This is because if you try to send emails to people who don’t understand why they are receiving emails from you, they will most likely mark the emails as spam or complaints. They even report it to get your domain blacklisted most of the time. And, since purchased lists have a high complaint rate, Amazon will instantly block your AWS account. Also, MailBluster strictly follows AWS Acceptable Use Policy. It clearly states that you are not allowed to use Simple Email Services (Amazon SES) to distribute, publish, send, or facilitate the sending of unsolicited mass emails or other messages, promotions, advertising, or spam.

Please note: MailBluster only supports sending marketing emails to authentic subscribers and subscribed lists. MailBluster does not provide any email IDs or subscriber lists.

You can only view the number of subscribers for your Brand over a time period of 24 hours only on the Dashboard of MailBluster.

First, go to Leads, then search or select that specific lead. Click on the Lead>Activity and you will open up with a tab like this as shown below. You will see all the campaign activities of that lead for the last 90 days.

Details activities of the lead can be seen after clicking on the Campaign name

Please note: Only the last 90 days activity can be seen for any individual lead.

You can import leads to 2 kinds of already created segment: A/B testing segment and Static segment. You cannot import leads to Standard segment unfortunately.

For A/B Testing Segment

After entering the segment, click on Import.

Override lead means that when a lead is added to the brand, any existing lead information will be updated with the new details. This ensures that MailBluster leads database stays current and accurate with the latest information.

This information can be found from Your Brand > Add new > Add single lead

Deprecated means that in future versions, we may remove this information. This information cannot be used in MailBluster; we only store it. Since we have released the complete lead custom field feature, storing this information is no longer necessary.

Field

A field is a feature in MailBluster (under MailBluster > Fields) which allows users to place fixed values or merge tags: ID, First name, Last name, Full name and Email address inside subject, email content (email body) and inside every lead information.

The following shows the Fields containing only the default merge tags.

Custom Field

A custom field is a feature in MailBluster (under MailBluster > Fields) that allows users to define specific data fields to their unique needs or requirements. These fields are not predefined by the system but are created by users based on their specific use case or context. Custom fields enable users to capture and store additional information beyond the standard or default set of fields provided by MailBluster. It can be used inside subject, email content (email body) and inside every lead information.

The following shows the Custom Fields containing the user defined field tags or custom merge tags.

To create Custom Field in MailBluster, go to Fields section and then click on Add new.

Enter Field label and then Field merge tag will be auto generated.

Here we used the Field label “State” and Field merge tag “state” is auto generated instantly.

Now we can use this custom field “State” in Leads, Standard Segment, Forms and Campaigns quite easily. Here are some examples:

In Add Lead:

In Standard Segment:

In Forms:

In Subject of Campaigns:

In Edit Content>Compose mail under Campaigns:

The maximum character limit of the lead field is 50 characters long.

Also, custom fields can be a maximum of 50 characters long. It will get saved if you change the value to or within 50 characters. Otherwise, it will not exceed more than 50 characters.

MailBluster has Custom Merge Tags that can be used in Leads, Email Subject as well as Email Body.

Now with new custom field functionalities, you can import leads, add/update lead, export leads and view leads with custom fields.

You can go to your Brand > Fields and set your own custom field which you can use in you Email Subject and Body.

Here we added a custom field or merge tag named “Gender”

Merge tags can be applied to Subject of the email campaign

And, Body of the email campaign as well

The more custom merge tags you added from Brand > Fields, the more tags will be added here in Merge tags for example: Gender which was added later.

The sent email received by the subscriber will be like this:

When a lead’s Subscription status is ‘Unsubscribed” but their Double Opt-In status is ‘Confirmed’, that means that the lead initially subscribed and confirmed their email address but later chose to unsubscribe from your emails.
