You might already have an SMS provider that you use so here is 6 questions to ask your bulk SMS software supplier so you know that you are getting the best that money can buy.
You will need to ask if the bulk SMS pricing is transparent. Many companies have tiny little details in their prices so what appeared to be a good deal ends up to be more expensive than you thought.
Reliability can be an issue with some companies. So what you will need to ask is, does the company use a direct connection to the UK networks? Other connections can suffer real reliability issues.
Sticking with the reliability theme, where are the company’s servers hosted? How reliable are they? Is there a back up plan if all servers go down?
Do they provide an opt-out/unsubscribe tool as no cost? You need to provide this unsubscribe option on your messages otherwise you could fine yourself breaking the law.
What are there payment options? Can you buy online automatically and also pay by invoice? You might find some companies will penalise you for that.
It is important that you are using a company that is trusted and has a wealth of experience working with big names and little ones. A company that will get involved if needed a make sure that your campaign is a success.
