Yes but remember by clicking to submit an entry, regardless of payment, you will automatically be liable for paying for that entry, even if your client later decides to refuse permission. The online application requires you to give your client’s name and their email. After you submit an entry, your client will receive an automated invitation to see the entry detail linked to their name, which they can authorise online or authorise offline to MAA. There will be a period of one week for MAA to receive your client confirmation after the latest closing deadline of 17th October 2016 (ie. all client signatures must be provided by 24th October to enable judging). The terms & conditions state that all campaign entries must be signed by your client: essentially this is to protect the MAA using your entries for judging purposes and in winners publicity. You should seek client approval well ahead of the closing deadline and plan who will sign your entry online by the client organisation in advance of any holiday/unforeseen absence. The MAA will automatically send an email to you confirming receipt of client authorisation, but it remains your responsibility to chase your client to sign (as needed).
Please add email@example.com to your safe senders list to ensure email notifications are received and advise your client to do the same.
