I don't know Spanish. Sorry!
The first hundred went fine.
If a certificate was created for the rest of the certificates, you can delete those.
To resume, delete the information in the four columns that Autocrat adds.
Run autocrat again and it should pick up where it left off.
With a personal account like yours, you are limited to 100 emails in a 24-hour period.
If you have more than a 100 left, put anything in the status column for the extra rows. Autocrat should ignore those rows that can be processed the next day.
