Beauty Bloggin' Tip: When you reach out to a company to do a giveaway or some sponsorship....
1) Don't reach out to everyone in One Email or Instagram Post..or Tag them.
2) Don't reach out to two companies and ask for Blue lipstick from both (just an example). Everyone wants to help and be part of it but at the end of the day its business for them. So if you are asking for a specific item for your "goody bag/giveaway" make sure it is different.
Try sending a personal email explaining your company, what it is for and any helpful information. If you must send a blast email try using BCC. If a company is taking the time to send you product take the time to email them personally.
If a company cannot help sponsor don't take it personally. Sometimes it is just not in the budget.
I hope that helps and let me know if you want more little tips and tricks
