Hello, You have a big list of 12K emails that not an issue. I will recommend you a platform that can also handle if your list would have been much bigger then it is. Even if you would like to have them working for you that is also possible, you can let them know when to runn the campaign and when to start the new one (all that). However they only provide dedicated stuff to there customers, SMTPs, IPs and Domains are clean enough to deliver the emails to the recipient inbox. "Imailunlimited" . They also have a service of Ravage that is only for big lists you can see at "ravage.imailunlimited" The software is amazing and the features are remarkable IP rotation, Domain rotation, Live Reports ( Opens + Clicks + Deliveries + Bounces + Blocks) and Test Send + Spam test Feature is really nice. I would highly recommend you to please try them once you won't be disappointed by my suggestion. Thank you so much for your time.
