Dear list,
is it fair/correct to check the existence of a mailbox for about 30/50
mail addresses/day?
They quite always will be present unless misspelled or typo that may be
a couple in a month.
We must RSET and then QUIT every the smtp connection just after the RCPT
TO answer because we must check the data but we cannot contact these users.
We actually are checking the domain and MX existence.
Do you think that we may be blocked or reputation decreased if we
activate this kind of recipient checking process?
Note: we are not going to send them any e-mail also after this process,
this isn't a database verification but a paper collecting process.
Long explanation (preventing the double opt-in and bad-collecting
process objections):
Our customer collect e-mail addresses written over *paper signed
contracts* (they sell contracts in behalf of an energetic company).
The process we manage for them is a sort of CRM that collect, sanitize
and send data to the energetic company via API in different steps
(required in their technical flow).
We (and the customer) cannot send any e-mail to the end user due to the
agreement (sell mandate). Our customer act in behalf of the energetic
company, also the privacy consent don't give him the right to send any
e-mail to the final user. Only the energetic company that is the data
owner can contact them, we (and our customer) act as "external data
processor" we only act what the data owner request us and they request
not to contact the customer after the contract is signed.
If a wrong address is inserted, our customer doesn't get paid for that
contract. If more than 1 error is present in the same period, he risks
also to loose the sell mandate because that e-mail address is also used
to recognize and de-duplicate customer (both with phone number and
physical address), so it may became a serious duplication issue to
manage for the energetic company and a serious damage for our customer
not to check the existence of the address.
Thank you all!
