Improve your campaigns' performances thanks to our expertise

Get rid of invalid addresses (hardbounces):

2Cost /1000

An invalid address (aka a “hardbounce”) is an address that cannot open your email campaign in any circumstances.
So it pointlessly inflates the cost of your campaigns and is a potential risk to your ability to deliver.
An invalid address may be an address that used to exist but was deleted by the user (or his/her company) or an address that was misspelt or mistyped.
To improve your dispatches , MailKitchen provides you with its detection and file cleaning technology, enabling you to target only verified addresses.

  • What is an invalid address (hardbounce)?

    It is an address that cannot open your email address under any circumstances.
    The address may have been misspelt or may no longer exist as a result of being deleted by the owner.
    An invalid address is generally called a hardbounce, or sometimes just undeliverable mail.

  • What risks arise from a significant number of invalid addresses?

    On top of the additional cost incurred by sending emails to non-existent addresses, invalid addresses also pose a real risk to your ability to deliver (“deliverability”) your email campaigns.
    If an email provider notices an excessive proportion of emails sent through its servers to invalid addresses, your campaign may be simply blocked, making even partial delivery impossible.

  • How much will cleanup cost?

    No nasty surprises with MailKitchen, as the price is fixed at €2 (excl. tax) per batch of 1,000 verified addresses.
    That means we offer to check 100,000 addresses for you for €200 excl. tax

  • How long will cleanup take?

    This file will contain a .csv file (readable in Excel or Notepad) that shows all the information of the original file along with a new column showing information about the check (valid and invalid addresses, etc.).
    It will also include a precise statistical report with graphics in a .pdf

Remove dangerous addresses (spamtraps and honeypots)

2Cost /1000

An email database may include, in spite of the diligence and professionalism of the company that gathers the addresses, dangerous addresses subject to “spamtraps” or “honeypots”. These can be added through registration forms by malicious competitors or may be old addresses that used to be valid but are now run by companies that wish to use them to boost the impact of specialist blacklists.
To increase the performances of your dispatches, MailKitchen provides you with our detection and file cleanup technology, enabling you to target only verified addresses.

  • What is a dangerous address (spamtrap and honeypots)?

    There are many different kinds and origins of dangerous emails. But the main ones are “spamtraps” and “honeypots”. Spamtraps are addresses used by specialist lists that aim to tackle spam. But such addresses can be added to your databases by malicious competitors through registration forms, for instance.
    The lists that then use these addresses aim to save your email (content, subject, name of sender and brand/product, etc.) and mark you down as a spammer.
    Honeypots are addresses that genuinely exist and may have been used by real web surfers. But once these surfers decided to stop using these addresses, the messaging provider did not deactivate them to measure the rate of unsolicited email that can be sent to them.
    In both scenarios, the addresses could get your campaign - and maybe even your routing solution – blocked and, in extreme cases, result in your brand/name/etc. Being marked down on specialist lists so that all your future campaigns will be rejected.

  • What are the risks of having a significant number of dangerous addresses?

    On top of the additional cost incurred by sending emails to non-existent addresses, invalid addresses also pose a real risk to your ability to deliver (“deliverability”) your email campaigns. The specialist operators concerned (who use so-called dangerous emails) will cause your campaigns to be blocked. In the best cases such blockages will be temporary (several days ) but in extremes ones they could be permanent.
