20th July, FIFA Women's World Cup

There's not much that unites people in the way that football does and the World Cup is always a great opportunity to provide special email content for your subscribers. Whether you're helping them prepare to watch the big game at home with friends and family, or hosting your own viewing party.

24th July, World Day for Grandparents and the Elderly

While Mother's Day and Father's Day are both widely celebrated, World Day for Grandparents often receives less attention. Think outside the box and use this occasion to put together a gift guide or dedicated promotion.

30th July, International Friendship Day 

For International Friendship Day, why not promote fun activities for friends to do together? Alternatively, a 2 for 1 offer could also be a great campaign to encourage sharing and spending time together.
