Good morning Joe,
The following is only my opinion and is not set in stones!!!
Indulgence is a beautiful thing, and I know it's at the core of the Xxxxx brand.
That first word 'indulgence' may plant the seed that buying a domain name is in itself indulgent and not necessary or important to their business. I would suggest something along the lines of 'Diamonds are forever. Much like a website. We may just have the perfect domain name which will strengthen your core brand identity.
I'm reaching out to discuss a domain name we're offering that speaks to the fleeting desire to indulge in the luxury of diamonds:
Not sure that everyone who is not in our business knows what a domain name is so better I think to contextualize it and relate it to websites if possible.
Make / It / Snow [com]
The concept of "making it snow" is already a well-known nod to opulence. Attaching it to the Xxxxx brand could make it legendary.
Again, I would attach less importance to opulence and more importance to having the best fit domain name.
In a world where people are buying less diamonds, perhaps what consumers need is a little nudge toward excess: "Make it magical. Make it snow"
It's never a good idea to point out the negatives in any given industry as they might see that as another reason to not spend money and thus not buy your domain name. Also, I think 'Make it magic. Make it snow' sounds better than magical.
Let's talk. Shall we?"
Again, I would say something along the lines of 'I'd love to hear your thoughts.' Or, something that evokes a sense of intrigue, or a sense of wanting to know more.
Don't shoot the messenger as these are just my opinions and are by no means flawless.
There are many things written about outbounding mails and the like and every situation is different. Check the company's website and external communications for the style and tone of your response. Is it high end and totally professional or jokey and casual. Do you know anything about the person you are writing to?
As they say, you only get one chance to make a first impression.
Good luck.
Regards,
