This is not about comparing existing methods aimed to certify –or register– emails, but about comparing the features and pricing of several products on offer.

eEvidence it’s based on a patent pending methodology, as it is in many ways unique. This makes it difficult to determine whom can we compare our product with. Nevertheless, in spite of their totally different approach, we have reviewed some relevant products in order to get a clear idea of what each has to offer.

1. What about the cost of registering an email

Plans from one product to another differ greatly, making it hard to compare these side-by-side. We can, however, compare the cost for a given scenario and see how these compare. So, how much does it cost to certify 1,000 emails?

eevid.com 49€ for unlimited users
lleida.net Starting at 1€ per email
rpost.com 160€ for single users
mailcertificado.com 1,210€, lasting 190 days only
confirmsign.com 495€, limited to 500 MB a year
logalty.com Starting at 6€ per email
notificados.com 5.23€ per email
evicertia.com Starting at 5€ per email

2. Is the product cost-effective at massive scale

By massive we are not referring to thousands of emails, but to millions. In compliance scenarios, for instance, companies are in need of better and more secure ways to communicate with others. Can this be achieved at a reasonable cost?

eevid.com Yes, for as low as 0.005 euro per email
lleida.net No
rpost.com No
mailcertificado.com No
confirmsign.com No
logalty.com No
notificados.com No
evicertia.com No

3. How are emails supposed to be sent.

When looking for email certification products, a common question is how are we supposed to send our emails. Can we send it as we normally do, from our email system or service, or do we need to use a third party platform to compose it and ultimately send it? The fewer the changes, the better.

eevid.com From your current email system or service
lleida.net From your current email system or service with the provider on copy
rpost.com From their platoform or by means of a plugin from your current email client
mailcertificado.com From their platform
confirmsign.com From their platform
logalty.com From their platform
notificados.com From their platform
evicertia.com From their platoform or by means of a plugin from your current email client

4. What do recipients actually receive.

When registering emails sent to others, we must consider how unobtrusive the registration process is. Do we want the recipient to know about it? So, what do recipients actually receive from you?

eevid.com A regular email sent by you with no indication about the registration process
lleida.net A regular email from you and a second email from the provider with an indication about the registration process
rpost.com An email from you with a default indication about the registration process
mailcertificado.com An email notice from the provider with a link to retrieve the message from their website
confirmsign.com An email notice from the provider with a link to retrieve the message from their website
logalty.com An email notice from the provider with a link to retrieve the message from their website
notificados.com An email notice from the provider with a link to retrieve the message from their website
evicertia.com An email from the provider

5. What are the email size limitations

When registering for an email related product or service, it is important to find out whether there are any limitations that may cause inconvenience. For instance, the limit on the size of an email message could be extremely relevant. With today’s bandwidth capabilities, anyone would agree that some limits would be simply unacceptable.

eevid.com 50 MB each
lleida.net 5 MB each
rpost.com 25 MB each
mailcertificado.com 6 MB each
confirmsign.com 3 MB each (monthly bandwidth limits apply)
logalty.com Doesn’t say
notificados.com 4 MB each
evicertia.com Doesn’t say

6. How long is the digital evidence available

Digital evidences often last just a few years, specifically as long as the digital certificate in which they are based remains valid and unexpired. How long will the evidence you are paying for be valid is something you need to know in advance.

eevid.com Forever, at no additional cost
lleida.net 5 years
rpost.com Doesn’t say. A fee applies for decrypting a receipt.
mailcertificado.com 5 years
confirmsign.com Doesn’t say
logalty.com 5 years
notificados.com 5 years
evicertia.com 5 years

7. Are there free plans available

Beyond free trials and demos, the question here is simple: can you register to use the product forever for free? In other words, are the products based on a freemium business model?

eevid.com Free up to 25 emails a year
lleida.net No
rpost.com Free up 5 emails a month
mailcertificado.com No
confirmsign.com No
logalty.com Doesn’t seem like
notificados.com No
evicertia.com No

8. Do recipients know about it

Letting others know that you are registering the emails you send them may not always be seen in a good light. Are you registering your emails because you distrust them? If not, why? Some products require the recipient to intervene, whilst others don’t even need them to know about it. It’s up to you to decide what suits you best.

eevid.com Doesn’t require the recipient to know or intervene
lleida.net Yes, the recipients receive two emails
rpost.com Up to the sender
mailcertificado.com Action from the recipient is mandatory
confirmsign.com Action from the recipient is mandatory
logalty.com Action from the recipient is mandatory
notificados.com Action from the recipient is mandatory
evicertia.com Yes, the email has an indication about the process

9. Are there any other relevant features

Attempting to compare products based on all available features has proven to be a nightmare, mainly because there are almost no features in common. Moreover, most product descriptions are really complex and even unclear on what each plan does or does not include. Focusing on the essentials, we believe there’s only one feature that is worth comparing: do the products include storage of the emails and certification files?

eevid.com Unlimited storage of all emails and files, forever
lleida.net Yes, for a limited time
rpost.com No
mailcertificado.com Yes (no additional details)
confirmsign.com Yes (no additional details)
logalty.com Yes (no additional details)
notificados.com Yes (no additional details)
evicertia.com Yes (no additional details)

10. Is the product suitable for software integration

The need to generate digital evidences of what is sent via email is usually greater within organizations than for an individual. There are countless business processes that include email communication of sensitive information, all based on enterprise software solutions. How suitable is each product in terms of software integration?

eevid.com Straightforward, fully based on standards
lleida.net Available API (no additional details)
rpost.com Requires server based solution
mailcertificado.com Based on web services (no additional details)
confirmsign.com Doesn’t say
logalty.com Doesn’t say
