Why Emailbidding is not an Affiliation network?
Emailbidding is not an Affiliation Network because we segment the audience that will receive the message in a way that an Affiliation Network doesn't.
In this type of network the main goal is to spread the word about a product/service everywhere and to everyone (with banner ads for example). With us, the recipients will only receive information that is useful and interesting for them. We deeply respect the subscriber.
Can I place Javascript on my email kit?
No!
We can’t accept that as many email providers block this feature.
Why shall I use Emailbidding default templates?
What category should I choose for my campaign?
Example: For a campaign promoting young men's clothes, you should choose the category "Apparel" and not "Games & Consoles". The category represents what your campaign is all about and not who you want to target. If you want to target young adults, select the age range on the next menu.

How to implement a Suppression List?
- If your suppression list has no more than 200.000 email addresses, you can upload it directly on the platform while setting up the campaign, under menu “Options”. Once the campaign is submitted, the file will be automatically processed into the database to be excluded by algorithm.
The file must be in .csv, .xls or .txt format. It must have one email address per line. The email addresses can be encrypted with "MD5".
2. On Emailbidding’s SFTP, you will have an exclusive cloud space available where you can put your suppression lists. An operator then will manually pick up the file and process it into the database to be excluded by algorithm once the campaign starts.
Step 1: Request a username and password by sending an email to support@emailbidding.com or by contacting your Emailbidding Account Manager. You should indicate the campaign name. Step 2: Fill the following fields: Host: sftp.emailbidding.com, Port: 22122, User and Password.

Why Emailbidding is not an ESP?
We are not an ESP simply because our platform doesn't focus on quantity, but rather on quality. Our main goal is to maximize results, both on clicks and opens, not the number of emails sent.
We reach the audience you want!
Why can’t I login with my credentials?
You need to check when was the last time you've logged in in our platform!
As explained in our Terms and Conditions, an account is automatically canceled if the user doesn't use its account for at least one year, without prejudice of other contractual, legal or tax obligations that, by its nature, should survive termination, such as any pending or due payment.
If this is not your case, please contact our support center and we'll guide you through the process. Just click on the "Contact" option on the top or bottom of the page.
What is an Unique Click?
An Unique Click means any number of clicks on any Link inside a campaign email, by a single subscriber, made within one hour counted from the first click, which means that if several clicks happen in one single e-mail within one hour since the first click occurred, only one unique click will be considered.
Emailbidding uses only unique clicks for its performance measurements. We do this because we believe this is the only fair way to present good quality results to our advertisers.

What is the CPC (Cost-per-Click)?
CPC (cost-per-click) is the amount of money the advertiser is willing to pay per click. Bear in mind that Emailbidding only counts Unique Clicks for performance measurements and billing. The CPC also influences your campaign Factor that will be responsible for your campaign performance.
On Emailbidding, Advertisers define how much they are willing to pay for each click, but Publishers can also define a minimum or maximum CPC for their database(s).

What is the Billable Unique Click?
The Billable Unique Click is the campaign's first click (the unique click) made by the subscriber. Even if a subscriber clicks several times on the email, for the next 60 minutes only one click will be billed.
Since opens and clicks can be performed several days after the email has been sent, Emailbidding counts all the unique clicks made in the next 30 days after the email has been sent.
What is the Click-Through Rate (CTR) or Click-Through Open Rate?
What is the CPM (Cost-per-Mille or Cost-per-Thousand)?
The CPM (Cost-per-Mille or Cost-per-Thousand) is the cost of a thousand emails sent. CPM is a commonly used unit in advertising. It is used in marketing as a benchmarking metric in order to calculate the relative cost of an advertising campaign or an ad message in a given medium.
Here is the formula:
What is the Budget?
To read more about unlimited budgets please click "What are Unlimited Budgets?"
What are Unlimited Budgets?
In Emailbidding platform, you can set your campaign budget as unlimited. If you do so, you won't be limiting your campaign perfomance with a certain amount, letting it reach the maximum volume possible of clicks and opens.
You can always see the estimated total spending in Estimated Perfomance at the menu Targeting and Bidding.
What is the Factor?
The Factor is a proprietary algorithm implemented by Emailbidding based on your campaign's opens, clicks, rate of unsubscribes, spam complaints and bid, collected throughout the different stages of your campaign. The factor is calculated by comparing your campaign with others that are competing for the same segments.
The campaign rank position (determined by the factor) defines the sending priority in each segment. Our algorithm promotes the success of all campaigns, always trying to send your message for the subscribers that are more likely to be interested in it.
Does the bid influence my campaign performance?
Publishers have databases with different quality levels and they might require a minimum CPC for each of them. Your campaign might be influenced if its CPC doesn't reach these undisclosed values, since the most premium lists are likely to have a higher payout.
Another scenario occurs when two or more campaigns, that are competing for the same subscribers, have similar performances - as a marketplace, the one with the highest bid will get more volume of emails sent.
How do I remove the external domains from my campaign?
Step 1
Click in the yellow exclamation mark button to check if there are any errors. If your campaign contains any external domains, a message will show up on the top right corner of your screen, showing a short explanation on what external domains are present in your campaign - they can be in the "Design content", "Plain Text Content" or in the HTML Source.

Step 2
After the errors are shown, search for them inside the corresponding area ("Design content", "Plain Text Content" or in the HTML Source). After you find the detected errors, just remove or change them.
Bear in mind that when the external domain is detected in the HTML, many times they are inside fields such as "title=" and they will have to be removed. Bear in mind that a correctly inserted domain is inside "href=" or "src=" fields. All the other fields can't contain external domains.

After you have performed the changes, please repeat Step 1 to check if there are any other errors. Do not forget to save and submit your campaign.
To check how to insert links correctly in your campaign check “Adding Links to My Campaign”
What is the Pre-Header?
The Pre-Header is a small phrase that usually appears on your incoming email list, right next to the subject (e.g.: Gmail, Hotmail, Yahoo). When not defined, the Pre-Header assumes the first words contained in the email message.
With this feature, you will be able to use the pre-header as a strategic complement to help boosting your campaigns' openings.
Ideally, this text should be a striking phrase, something to induce the subscriber to open the message!

My Campaign is “Not Ready”, what is this?
If your campaign has the status “Not Ready” and you have already made all the changes you wanted to your campaign, you just need to click the submission button (arrow) to submit it.
If the button isn't clickable it means you need to save the campaign first. After that, the submission button will be enabled.
My Campaign is “Warming up”. What does this mean?
The Warming-Up stage is the first stage of your campaign. Your campaign is active and running but limited to a certain volume of emails during the first 2 to 3 days (the days and volume depends on the country where the campaign is running).
This happens for two reasons:
1. The first one is to assure to the Advertiser that if the campaign has any problem, there is a 2 to 3-days period to correct it without a large volume already been sent.
2. The second reason is to test the subscribers' behaviour, sending it to selected subscribers and allowing the algorithm to make an accurate selection of the micro-segments that are more interested in your message. This assures that when the campaign is running full speed, the emails sent will be focused only on the segments of subscribers that have shown more interest, allowing it to increase click rate, open rate and also conversions.
Thus, the warm-up period will maximize the campaign's performance and give you a higher delivery quality.
Tip: Check the Detailed Statistics to see the the open and click rates by gender, location and age. This can help you to achieve a more accurate segmentation and a better understanding of the audience interested in your campaign.
What is a suppression list?
A suppression list is a list of email addresses that the Advertiser doesn’t want to send his campaign to.
To add a suppression list to your campaign you can upload it in the Advanced Setup menu. Note that all the suppression lists need to be upload by campaign and not by Advertiser even if the campaign is duplicated.
Can I recover archived campaigns?
To recover a campaign that you have already archived, click on the duplicate button, choose a name to the new campaign and then click on “Duplicate Campaign”.
Note that this action will duplicate your campaign by creating a copy of the email kit but not suppression lists.
The new campaign will be added as "draft" to your campaign's list.
What is the difference between “Send Date” and “Event Date”?
To have a full view of your campaign statistics you can either select to see the information organized by send date or event date. So you can choose to see what is more important to you!
Statistics saves all the campaign's information that is useful to analyze the its performance and daily cost.
When Send Date is selected, the events are shown according to the day in which the email has been sent, no matter if they happened on a different day or not. This option is very useful to monitor the campaign performance according to the date the emails have been sent.
When Event Date is selected, the events are shown according to the day they have occurred. This option is very useful to monitor the costs of your campaign.
Tip: We recommend you to use the options on the left to select the different filters you want to apply (like filter per day, campaign or country).
To see more about statistics and rates check: “Boosting My Campaign Performance” or “Boosting My Campaign Conversion”
Why did my campaign decrease the volume of emails send?
The major reasons to why a campaign has lowered the level of emails sent, are:
- It stopped being competitive - solution: increase the Bid;
- It has a high level of unsubscribes - Emailbidding worries about all the participants in the marketplace, this way even if a campaign has a good performance, a high level of unsubscribes will be harmful to the Publishers' database(s). If this happens, the competitiveness Factor will decrease and the campaign will lose volume (or in worst cases even stop completely) - solution: change the segmentation and rethink the target audience.
- Has been running for a long time - if a campaign is running for a long period of time with the same promotion, email kit and subject, then it will likely see a decrease of performance since the subscribers may be unhappy for receiving it continuously - solution: rethink the campaign's duration strategy and change the email kit and subject in a more regular basis.
My campaign has finished. Why are the clicks increasing? Are they billable?
This situation is described in our Terms and Conditions, where the due payment of all the Unique Clicks generated within 30 days after the campaign finished, shall be invoiced by the Data Processor to the Data User.
So even if a campaign is scheduled for just 2 days (for example), the clicks are tracked and billed on the next 30 days after the email was sent.
